This paper assesses the exact function of the complement introduced by EN in structures such as Elle a teint ses rideaux en rouge (literally, She dyed her curtains ‘in’red). Since these complements answer the questions How ?, the possibility of viewing them as object-oriented manner adverbials is first investigated - and discarded.They are then paralleled to the secondary predicates already indentified for other resultative constructions. But I show that they depart from the complement of inherently resultative verbs such as mettre (cf. literally ‘put X in anger/put X pregnant>’), which direcly select either a PP projected by the preposition EN or an AP. WE propose that they pattern rather like transformer (cf. lit. ‘transform X in frog’) : the complement corresponds to a resultative augmentation of the argument struture of the verb, with EN (lit. ‘in’) acting as a Result functionaml head selecting either for a NP (with transformer) or an AP ( with teindre).
