used to show which one of two or more things you mean, especially the one that is closer to you or more directly under discussion.

João chose this option instead of the more expensive monthly plan.
- that
refers to the one farther away or less directly under discussion
文法句型
this + noun + (prepositional phrase / while-clause)
用法筆記
This sense often appears in structures comparing 'this' with 'that' or 'the other'. It depends on physical pointing or context that makes the contrast clear. Distinguish from sense 1, which does not involve comparison.
this — adverb
1. used to say that something is as much, as big, or as extreme as what you can see
used to say that something is as much, as big, or as extreme as what you can see, hear, or have just experienced — for example, holding your hands apart to show that a fish was [this] wide, or saying that you did not know a train ride would be [this] long.

this + adverb (far), modifying distance

- so
wider use — 'so' works without a visible referent and is acceptable in formal writing; 'this' needs a present reference point
- that
used for a degree away from the speaker ('Is it really that far?'); 'this' is closer to the speaker
- as … as this
more explicit but less common in everyday speech ('as big as this' instead of 'this big')
文法句型
this + adjective
this + adverb
用法筆記
The speaker must have a clear referent — a visible object, a measurable amount, or a previously mentioned standard — that establishes what 'this' degree refers to. Without such a referent, use 'so' instead (e.g. 'I didn't know it was so hot' works alone; 'I didn't know it was this hot' implies looking at or feeling the heat right now).
常見錯誤
this — determiner / pronoun
1. points to a person, object, or situation that is physically or temporally close
points to a person, object, or situation that is physically or temporally close to the speaker — for example, the chair you are sitting on, the room you are in, or today's date. Often contrasts with 'that', which refers to something farther away.
Eli picked up this book from the table and showed it to his mother.
demonstrative determiner: this + noun phrase
The view from this window is much better than from that one.
contrast: this vs that
Can you help me carry this box upstairs for Nora?
This train goes directly to the airport every thirty minutes.
Wei prefers this chair because it is softer than the other one.
- that
contrasting determiner for things farther away; the pair 'this/that' defines spatial or temporal distance
- that
refers to something farther from the speaker in space or time
文法句型
this + noun
this one
this is / was + noun phrase
用法筆記
Subject position patterns: 'this' as determiner naturally pairs with a following noun (this room, this idea). As pronoun, 'this is' starts a sentence that identifies or presents something. Unlike 'it', 'this' draws attention to the specific referent rather than just referring back to it.
常見錯誤
2. points back to a person, thing, or idea that has been mentioned earlier in the c
points back to a person, thing, or idea that has been mentioned earlier in the conversation or text, so the listener knows which one the speaker means.

anaphoric reference: replaces previously stated event

The doctor gave Baraka some medicine, but this treatment did not help.

Marco finished his report on Monday, and this document is now on my desk.
文法句型
this + noun (referring back)
this is/was + noun phrase
this + noun phrase + of + possessive
用法筆記
Distinguish from sense 1 (NEAR IN SPACE OR TIME): sense 1 requires physical or temporal closeness to the speaker; sense 2 works even when the referent is distant, as long as it was previously named in the discourse. Common in academic and formal writing to maintain reference without repeating a noun phrase.
常見錯誤
3. said when telling someone who you are, or when making two people known to each o
said when telling someone who you are, or when making two people known to each other for the first time — for example, at the start of a phone call or when introducing a friend.
Mom, this is my friend Dewi from the swimming club.
presentational: this is + name + role description

phone introduction: this is + name
And this is our new teacher, Mr. Chen, who will teach history.
Nadia, this is my cousin Wren — she just moved to the city.

- meet
verb used in invitation to an introduction: 'Come meet my brother.'
文法句型
this is + name
this is + my + noun
this is + name + — + role description
用法筆記
Fixed formula: 'This is…' is the standard way to introduce people in English. Unlike sense 1, it does not point to physical proximity — the person being introduced may be standing next to you or on the phone. In phone calls, 'This is [name]' is used by the speaker identifying themselves, not the listener.
常見錯誤
4. said when drawing someone's attention to something, often using a hand gesture o
said when drawing someone's attention to something, often using a hand gesture or by holding the object up — for example, pointing at a photo, showing a new item, or directing someone to look at something specific.

imperative + look at this + noun clause
You need to press this button here to start the machine.
Baraka showed the class this photo from his trip to Japan.
Sahil found this wallet on the ground outside the library.
Listen to this song — I think you will really like the melody.
文法句型
this + noun (with gesture)
look at this
this is + noun phrase
用法筆記
Often accompanied by a physical gesture (pointing, holding up). The difference from sense 1 (NEAR IN SPACE OR TIME) is the speaker's communicative goal: sense 4 is about directing the listener's attention, while sense 1 is about identifying which referent is meant. Many sentences could fit both senses depending on context.
常見錯誤
5. used with words for periods of time — such as 'morning', 'month', or 'year' — to
used with words for periods of time — such as 'morning', 'month', or 'year' — to refer to the current one, the one that is happening now.

temporal determiner: this + weekend
This year the company hired fifty new workers at the factory.
Marco has been feeling tired this whole week because of the night shifts.
Evelyn hopes to finish her project by the end of this month.
Eli started his new job this morning and met all his teammates.
文法句型
this + time noun (morning, week, year, month, century)
用法筆記
Distinguish from 'last' (past time period) and 'next' (future time period). 'This' covers the current time period that includes the moment of speaking. For near future within the current period, 'this' can be used with 'weekend' or 'afternoon' even for parts that haven't happened yet.
常見錯誤
6. used when talking about something connected with a particular person, while show
used when talking about something connected with a particular person, while showing a feeling such as fondness, irritation, or sympathy — for example, saying 'this daughter of mine' with pride or 'this noise of yours' with annoyance.
I cannot believe this noise from your room at three in the morning.
emotive determiner expressing annoyance
Wren has been working hard on this project of hers for many months.
structure: this + noun + of + possessive pronoun
I really like this painting of yours — the colors are so bright.
We need to talk about this attitude of his before it causes problems.
This dog of theirs keeps getting into the garden and digging holes.
- such
can express a similar attitude but without the personal connection: 'I can't believe such noise.'
文法句型
this + noun + of + possessive (this dog of yours)
this + noun + of + possessive's
用法筆記
The structure 'this + noun + of + possessive pronoun (yours, his, hers, theirs)' is the signature pattern. The speaker's attitude (positive or negative) comes from context and tone — the structure itself signals emotional involvement, not the type of feeling. Common in informal spoken English. Not used with simple 'my/your/his' as determiner — 'this my dog' is ungrammatical; use 'this dog of mine' instead.
常見錯誤
7. used in spoken stories as a determiner to bring up a person, thing, or event tha
used in spoken stories as a determiner to bring up a person, thing, or event that the listener has not heard about before, making the story feel more lively and immediate.

Ezra was telling me about this documentary he watched on deep-sea creatures.
文法句型
this + noun (new referent in story)
用法筆記
Only used in informal spoken narratives, not in writing. The thing or person introduced with 'this' must play a role in the rest of the story — if it is mentioned only once, use 'a' or 'some' instead.

- this situation
more explicit; used when the listener might not follow the pronoun alone
- these things
emphasises multiple separate items rather than a single state
- this mess
negative connotation; implies disorder or trouble
文法句型
this (as pronoun standing alone for a situation)
用法筆記
The referent of 'this' in this sense is usually understood from the context — the speaker may point to a messy room, a pile of paperwork, or a stressful life situation. It is common in phrases like 'put an end to this' and 'get through this'.
常見錯誤

Jin has been working at this company since last March.
The manager asked us to finish this project by Friday.
This medicine tastes awful but it helps my cough go away quickly.
- that
refers to something farther away in space, time, or the conversation
文法句型
this + noun — points to a specific nearby thing, person, or idea
用法筆記
Unlike a/an or the, 'this' specifically picks out one item from others near the speaker. The plural form is 'these'. Distinguish from sense 3 of the 'determiner, pronoun' POS (introductions) — sense 1 is about identifying an existing referent, not presenting a new person.
常見錯誤
2. used to introduce one person to another person or to a group — the speaker point
used to introduce one person to another person or to a group — the speaker points to the person being introduced
Rachid, this is my colleague Maeve from the marketing team.
this is + name/role for introducing someone

Everyone, this is our new teacher, Mr. Chen from Taipei.
I would like you to meet my sister Élise — she just arrived from France yesterday.
This is my business partner, Brandon, who runs the London office.
- meet
an imperative verb rather than a determiner; 'This is ...' is a fixed introduction formula
文法句型
This is + [name/role] — formal or informal introduction
Everyone, this is + [name] — group introduction
用法筆記
In introductions, 'this' stays singular even if you are introducing more than one person ('These are my friends'). The verb agrees with the noun that follows: 'This is my sister' but 'These are my parents.'
常見錯誤
3. used before an adjective of time, distance, or degree to mean 'already so' or 'a
used before an adjective of time, distance, or degree to mean 'already so' or 'as much as this' — emphasising that a situation has reached a noticeable extent
I cannot believe it is this late — I should have left an hour ago.
this + adjective (late) — emphasising surprising degree

this + adjective (long) — duration already reached
Is the train going to be this crowded every single morning?
Rohan did not expect the queue to be this long on a Tuesday afternoon.
I did not know the test could be this hard when I signed up.
- so
neutral and common across registers; 'this' adds a more conversational, emphatic tone
- that
also works before adjectives ('that long'), but implies a specific comparison; 'this' implies the current situation
- already
adverb of time, less flexible before adjectives; 'this' works as a determiner-like intensifier
文法句型
this + adjective — emphasizes a surprising or notable degree
用法筆記
This sense is informal and mainly British. It functions like 'so' or 'already' but with a stronger emotional colour — surprise, frustration, or emphasis. The adjective must express a scalable quality (late, long, hard, big, many). Not used with non-gradable adjectives (❌ 'this impossible').
常見錯誤

Constanza's tweet about the new policy got over fifty 'THIS!' replies within an hour.
- same
shorter and less emphatic; common in quick social media reactions but does not carry the same 'amplify' function
- second that
slightly more traditional and wordier; less common in short-form social media like Twitter or TikTok
文法句型
'THIS!' as a standalone exclamation
用法筆記
Almost always written with an exclamation mark ('THIS!') to convey enthusiasm and to distinguish it from the determiner 'this'. The longer form 'ALL OF THIS!' is also common for stronger emphasis. Avoid using this in formal or academic writing — it belongs to social-media and comment-section contexts only.
常見錯誤

a pronoun that points to a person, object, or situation physically close to the speaker, or to something the speaker has only recently started talking about — for example, pointing at a dish and saying 'This tastes amazing,' or holding up a phone and saying 'This is the latest model.'

the farther object or person
文法句型
this is + noun phrase
this + verb (intransitive)
this + verb + object
用法筆記
As a pronoun, 'this' replaces a full noun phrase and stands alone as the subject or object of a clause. It is most common at the start of a sentence ('This is…'), where it identifies or presents something. Unlike the determiner use, no noun follows — the referent is clear from context, gesture, or prior mention.
常見錯誤

used to refer forward to something that the speaker is about to say, write, or explain — for example, saying 'This is what I mean:' before giving an example, or writing 'This is the plan:' before listing the steps.

文法句型
this is what + clause

this + verb phrase + colon or dash
用法筆記
Distinguish from sense 1 (NEARBY PERSON OR OBJECT): sense 1 looks back or points to something already present; sense 2 points forward to something not yet stated. This is called a cataphoric use. The information that follows is always the content being introduced — the speaker treats it as a single unit: 'this' = 'the following statement or idea.'

adverb; used for location, cannot replace 'this' in all positions ('this is...' vs 'here is...')
文法句型
this is where + clause
this is when + clause
this is the + time/place noun
用法筆記
Distinguish from sense 1: sense 1 refers to any nearby item; sense 3 is specifically about the speaker's present location or the current moment in time. A useful test: if you can replace 'this' with 'now' or 'here' and the sentence still works, it is sense 3.
常見錯誤
4. used when choosing between two things to indicate the one that is physically nea
used when choosing between two things to indicate the one that is physically nearer, more relevant now, or more directly being examined — for example, pointing at two coats and saying 'I prefer this, not that,' or comparing two suggestions and saying 'This seems more practical.'

- that
the farther or less relevant option
文法句型
this is + noun phrase + not that
this one + relative clause
this + vs + that
用法筆記
This sense almost always appears in a contrastive context with 'that' — either explicitly ('this or that') or implicitly (the speaker is selecting from options). The difference from sense 1 is the comparative frame: sense 1 simply points to something present; sense 4 selects it as the nearer or more relevant item out of two or more alternatives.
常見錯誤
5. used in formal speech or writing to refer to the last-mentioned item when two pe
used in formal speech or writing to refer to the last-mentioned item when two people, things, or ideas have been named — for example, saying 'We discussed two options: leaving early or waiting. This seemed safer.' Here 'this' means 'the last one mentioned' (waiting), not the first one.

Minho considered jogging in the morning or going to the gym and decided this suited him better.
- the latter
formal alternative that removes ambiguity: 'the latter' always means the last-mentioned item

informal alternative: 'The last one seems better.'
- that
in this contrastive use, 'that' may refer to the first-mentioned item
文法句型
this + verb + and/but + that + verb
this + refers to + noun phrase
this was + mentioned
用法筆記
This is a classical 'anaphoric' use of 'this' where it refers back to the more recently mentioned item out of two. In many contexts, 'this' can be ambiguous — it may refer to either the nearer item in space or the more recent one in discourse. When precision is needed, formal English uses 'the latter' instead. Distinguish from sense 4: sense 4 contrasts items by physical or attentional closeness; sense 5 contrasts by order of mention in the text or speech.
