Does one use their with collective nouns such as jury?

Yes, the pronoun "their" can be used with collective nouns like "jury." In American English, collective nouns are often treated as singular, so one might say, "The jury has made its decision." However, in British English, it's common to treat collective nouns as plural, allowing for phrases like "The jury have given their verdict." Using "their" can also make the sentence more inclusive and avoid awkward constructions.
