Harm (v) is transitive because it's a causative verb
B means '
B to come to harm')
and all causative verbs are transitive. The subject is the cause and the object is the effect.
When a verb is nominalized (i.e, made into a noun), its argument(s) can be expressed,
generally as prepositional phrases. However, when a verb has both a transitive and an
intransitive form, like shoot:
- The hunters shot until they were out of ammunition. (intr)
- They shot the hunters for using all the ammunition. (trans)
either one of them can be expressed by a genitive with of -- i.e, the nominalization
- &the shooting of the hunters
is ambiguous (whence the "&" stigmatum) between the intransitive sense
- that event of shooting that the hunters did
and the transitive sense
- that event of somebody shooting the hunters
Either way, it's the Absolutive (subject of intransitive, object of transitive)
that gets picked to be the object of of.
That's if there's only one argument expressed. If both arguments of a transitive verb get expressed, they will still be possessive, but the subject will be a morphological genitive, while the object will be an of phrase. I.e,
B == Nominalize =>
A's shooting of
