Question

I'm looking for a shirt for my dad.
===============================
Does 'for my dad' modify 'shirt' or 'looking'?

Is 'for my dad' an adjective phrase or an adverbial phrase?

It modifies shirt, so is an adjective phrase.
Reed
The other fellow here is mistaken. If you were looking for your dad (who was missing), it would be adverbial, modifying "looking." In this case, it modifies shirt.
