Definition

'Theirs' is a possessive pronoun used to talk about something that belongs to them. It replaces a noun, so you say 'theirs' instead of repeating the thing.

Usage & Nuances

Use 'theirs' alone, not before a noun: say 'The book is theirs,' not 'their book is theirs' when replacing the noun. Do not confuse it with 'their' + noun. It is common in comparisons and ownership questions: 'ours or theirs?', 'Whose bag is this? It's theirs.'
