one sentence

[abcdeflearn1]

Some only pay ten bucks for something that they expect it to be worth double.


Should I keep "it" in the sentence?

Thanks

No, you already have something as a placeholder.

I certainly agree with Marius that the word "it" that you have in this sentence doesn't belong there, but my reason is somewhat different. In the subordinate clause with the subject and verb "they expect", the object (and subject of the infinitive "to be") it already there, that is, the relative pronoun "that". Thus there is no use for the word "it", which sits in a place where you might expect such an object.

Interestingly, the word "that" can be omitted in this sentence (although it is certainly fine to have it), but even if you do omit "that", it is "understood" to be there, so you still cannot have "it" as the object in the subordinate clause.

All crystal clear. Thanks a lot.
