用法筆記

Unlike the determiner 'their', the pronoun 'theirs' never stands before a noun. You cannot say 'theirs house' — instead say 'their house' or 'that house is theirs'. Many writers use 'theirs' (without an apostrophe) for a singular antecedent of unknown gender to avoid saying 'his or hers'.

常見錯誤

❌Theirs house is on the corner.
✅Their house is on the corner.' or 'That house is theirs.
💡'theirs' replaces the noun, so it cannot be placed before one.
❌The book is their's.
✅The book is theirs.
💡Possessive pronouns (yours, hers, its, ours, theirs) never take an apostrophe.
