Is it I who bother you? If I use 'me', does the verb change to 'bothers'?
Is it me who bothers you?
Thanks in advance.
The use of object-case pronouns as subject complements to the copula is not a rule but a widely tolerated deviation. If, therefore, by asking 'does the verb change?' you are enquiring about what is grammatically
correct, the answer is that there is no "correct" form for the verb in this situation, any more than there is a "correct" way to jaywalk or to run a red light!
If, however, you are asking whether it is
common practice to employ a third-person verb here, then the answer is yes, although many would justifiably argue that to construct the sentence thus is simply to compound one error with another (to extend the previous analogy, rather like spitting on the road as you jaywalk across it).
Standard formal usage requires nominative 'I' as complement here, which naturally requires a first-person verb, giving '...I who bother...'. I would strongly suggest that you stick to this tried-and-trusted formula, at least in any situation where you might be judged on the basis of your English skills!
