Commonly appears in two main patterns: (1) 'it is impossible (for someone) to do something', where 'it' refers forward to the infinitive clause; and (2) with a linking verb ('seems', 'became', 'is') describing the subject directly. The second pattern cannot take a following infinitive without restructuring.

文法句型

an impossible + noun (situation / position / task / choice)

make + something + impossible

用法筆記

This sense modifies nouns like 'situation', 'position', 'task', and 'choice'. It does not describe a person's character (see sense 3). Unlike sense 1, this meaning does not claim that something cannot be done at all — only that the difficulty is extreme.

常見錯誤

The meeting schedule was impossible.' (when meaning just 'difficult' — ambiguous with sense 1)
We were in an impossible meeting situation, with three urgent deadlines at once.
💡Using 'impossible situation' or 'impossible position' makes the sense clear.

    someone who is relaxed and flexible

  • reasonable

    someone who listens to others and behaves sensibly

文法句型

someone + is + impossible

someone + is being + impossible

用法筆記

Unlike sense 2, this sense applies to people. Using 'is being impossible' (the progressive form) signals that the behavior is temporary, not a permanent personality trait. This sense is informal and should be avoided in formal or professional writing.

常見錯誤

My boss is an impossible person.' (grammatically possible but sounds like a permanent judgment)
My boss is being impossible today.
💡The progressive form makes it clear you mean the current behavior, not the person's character.
