1. in a state where every item is in the exact spot someone wants it, with nothing
in a state where every item is in the exact spot someone wants it, with nothing crooked, untidy, or out of place; usually said about a room, desk, or display that someone keeps very neat on purpose.

- immaculate
stronger; means flawlessly clean and tidy, not only arranged the way someone wants
- orderly
more general; describes any organised state, can go before a noun
- spick-and-span
informal; emphasises cleanliness rather than precise arrangement
文法句型
just so
must be so
用法筆記
Predicative only — used after 'be', 'look', or 'want [something]', almost always with 'just' or 'exactly'. You cannot put it before a noun (no 'a so room'). Distinct from the adverb senses, which modify verbs or adjectives rather than describing how tidy something is.

Distinguish from sense 1: this sense usually appears with 'not' for softening ('not so cold' = milder than 'cold'). The pattern 'not so X as Y' is a softer alternative to 'less X than Y'.

tagged onto a sentence's final position, normally after 'much' or directly after a verb, to stress that the feeling or amount involved is very strong.

thank you so much
Roya missed her sister so much during the long winter.
verb + object + so much

文法句型

Almost always in the chain 'verb + (object) + so much'. Plain sentence-final 'so' without 'much' (as in 'I love it so') survives only in poetry and old-fashioned writing.

文法句型
so + auxiliary + subject

用法筆記
Subject-verb inversion is required: 'so does Brooke', not 'so Brooke does'. The auxiliary must match the previous clause's tense and verb. For the negative version, English uses 'neither' or 'nor' instead of 'so'.

stands in for a whole phrase or clause that has just been said, so that you do not have to repeat it — typically as the object of verbs like 'think', 'hope', 'believe', 'say', or 'guess'.

think + so
Andrés asked if the train was late, and the conductor said so.
Will Greta pass the swimming test? — I believe so.

occasional substitute, but 'so' is far more idiomatic
文法句型
think/hope/believe/say/guess + so
用法筆記
Distinct from sense 6: this 'so' replaces a clause as a verb's object ('I think so' = 'I think it will'). The negative is normally 'I don't think so', not 'I think not'. Verbs like 'know', 'agree', and 'see' do not allow this pattern.
常見錯誤

placed in a short reply with reversed word order ('so + subject + verb') to confirm that what someone has just pointed out really is the case, often with mild surprise.

so + I + have

文法句型

用法筆記
Distinguish from sense 5 ('I think so'): here 'so' starts a short reply and the speaker is confirming a fact they have just been shown, often with surprise. Word order is subject-verb, not the inverted verb-subject of sense 4.

7. added to a short reply to confirm that something just stated really is correct,
added to a short reply to confirm that something just stated really is correct, often when the speaker has only just noticed it or is mildly surprised.

文法句型

用法筆記
Always paired with the auxiliary or 'be' from the previous statement (so it is, so she has, so there is). Distinguish from adverb/6 (in adverb_b1): sense 6 simply confirms a prior situation, while this sense usually signals fresh recognition or mild surprise.
常見錯誤
8. takes the place of a previously used adjective, letting the speaker avoid saying
takes the place of a previously used adjective, letting the speaker avoid saying the same word twice — for example, 'the work is hard, and on rainy days even more so' means 'even more hard'.

Almost always preceded by a degree word (more, less, very, too, much). Most natural in writing or careful speech; in casual conversation people repeat the adjective instead.

用法筆記
Heavily stressed in speech and almost exclusively used by children, or by adults imitating children. The opposite move — denying that you did something — uses 'I did NOT' rather than another fixed phrase.

用法筆記
Often written with three dots after it ('So...') to show the trailing pause. Carries no real meaning; if you remove it, the sentence still works. Distinguish from sense 1 (which links back) and sense 2 (which recaps) — this one only buys the speaker thinking time.

用法筆記
Often paired with a follow-up clause that downplays the issue ('it costs nothing', 'it still tastes fine'). The speaker tone is calm or dismissive, never apologetic. Distinguish from sense 3 — sense 3 marks discovery and surprise, while this sense marks acceptance and indifference.

文法句型
main clause + so (that) + clause
用法筆記
Often followed by a modal verb ('can', 'could', 'would', 'will') in the second clause because the clause expresses a goal, not a fact. In informal English the word 'that' is usually dropped: 'I left early so I could catch the train.' Distinguish from sense conjunction/7 (THEREFORE): that one states a result that happened; this one states an intention.

文法句型
so as not + to-infinitive
用法筆記
More formal than 'in order not to'. The negative word 'not' must come between 'so as' and 'to'; placing it after 'to' ('so as to not...') is unidiomatic in standard British and American English. Used when the speaker wants to emphasise care or caution.
