Hello, I'm curious if or not a wh-word can be conjoined with another noun as a sentence subject.<br/><br/>For example, is it grammatically correct to say<br/>"Mary and whom did you go camping with?"<br/><br/>If not, what's the reason?<br/><br/>and what about "Mary and who did you go camping with?"<br/><br/>having trouble studying school grammar.... thank you!
