(By Jakob Lesage): "A causative is a valency increasing operation that introduces a causer core argument that makes a non-subject argument do or become something (e.g. ‘x eats’ -> ‘y feeds x’ = ‘y causes x to to eat’). Note that both causatives adding an argument to a transitive clause (I drink milk -> x causes me to drink milk) and those adding an argument to an intransitive clause (I sit -> x causes me to sit) are targeted by this question. This question targets productive, phonologically bound causative markers. Lexicalized causative verbs should be disregarded for this feature."
