Can an object be two parts of speech at once? thanks
The way I'm taking it, no.
It sounds pretty impossible for an object, which is described to be a noun, to also be another part of speech at the same time; but there are circumstances where a word could mean two different things, if that's what you're thinking about it.
For example, the word "book" can be both a verb and a noun.
Verb: We booked the flight for tomorrow.
Noun: I put the book back on the shelf.
