French employs 'être' (to be) as the auxiliary verb for a specific subset of verbs, particularly unaccusative and reflexive intransitive verbs, as demonstrated in linguistic studies on auxiliary selection.
The claim states that French utilizes 'be' as the auxiliary verb for a specific subset of verbs. Papers [0] and [11] directly discuss auxiliary selection in Romance languages including French, focusing on how specific subsets of verbs (such as intransitive or peripheral verbs) select between auxiliaries like 'être' and 'avoir'. The evidence directly supports the claim.
