Ooh… verbals are another fun one.
Basically, yes. A gerund IS a noun. A participle is an adjective when used as such. An infinitive is… whatever it feels like being.
But anyway, to get to the point…
I won’t claim that “my/his/her…” are purely adjectives, but I will make the claim that they’re as much adjectives as they are anything else.

















I love shorts.
They’re comfy and easy to wear.
