«نُزِّلَ الْفِعْلُ الْمُتَعَدِّي مَنْزِلَةَ اللَّازِمِ»
A transitive verb is treated, for this purpose, like an intransitive verb.
This is not a permanent morphological reclassification. The verb «يعطي» remains transitive in the language, but the specific utterance is concerned with the action rather than an object that must be mentally supplied.
«زَيْدٌ يُعْطِي» — Zayd gives: the characteristic of giving is foregrounded.
«زَيْدٌ يُعْطِي الدَّنَانِيرَ» — Zayd gives dinars: the class of what is given is now named.
One verb can therefore support different communicative purposes depending on what the context calls for.
