Floating quantifier is a quantifier that is not immediately near the NP it quantifies. French tous (all) is the exemplary case:
(i) a Tous les étudiants ont lu ce livre All the students have read that book b Les étudiants ont tous lu ce livre
In (i)a the quantifier tous immediately precedes the NP les Ã©tudiants it quantifies, but in (i)b tous has 'floated' off, as it were, into the sentence. Sportiche (1988) has claimed that tous in examples such as (i)b is stranded in the (VP-internal) D-structure subject position.
