Complex prepositional objects?

Tell it to whomever [that] lost the book. (Subj + Subj)

'that lost the book' is a relative clause in form, and an adjective clause in function: 'that' is the subject, 'lost' is the verb, and 'a book' is the object. The entire clause modifies 'whomever'. It tells us more about 'whomever'. (Note, a clause is tense. That is, a subject is not what makes a clause a Clause. That's why 'that' is often omitted.) <<<<

Of course. :-)


So, you see, 'lost' is not left without a subject. It only appears that way because 'that', its true subject, has been omitted. <<

But we cannot put "that" in the sentence.

Tell it to whomever [that] lost the book. (Subj + Subj)

It still appears to me that "lost" is without a subject.

mm.....

Whoever [it was that] lost the book needs to buy a new one.

Tell it to whomever [that] lost the book. (Subj + Subj)

I like this better, "Tell whoever lost the book that we have it here. They can come and get it whenever they want."

I don't think "to" is very likely to follow "tell". I think it best to reserve "to" for "say". Of course "to" can follow "tell", but I wouldn't call it the most typical thing to occur in English.

Did you tell them?

What did you say to them?

What did you tell to them? - Nah - don't like it.
