<i>Le prix est (de) 15 euros</i>
The status of copular constructions expressing quantification, such as “le prix est (de) 15 euros) is examined with respect to prototypical specificational constructions (<i>Le prix est quinze euros</i>) and to predicational constructions involving quantification. It appears that the copular construction expressing quantification ([NP_Cop_<i>de</i>_Q NP]) is a hybrid construction combining properties of both specificational and predicational copular constructions. In this sense, and according to the <b>inheritance network</b> advocated by Construction Grammar, ([NP_Cop_<i>de</i>_Q NP]) inherits features from both the specificational (e.g. the relationship between NP1 and NP2) and the predicational construction, but also develops its own idiosyncrasy.
