Question

Which additional word in the sentence should be capitalized? I called mom on my cell phone from the gymnasium around six o'clock. A. Gymnasium B. Phone C. Cell D. Mom

Answer 1

D. Mom should be capitalized because I believe it is a proper noun.

You can replace the word mom with a person's name. That is not always the case however. For example, I called my mom on my.... If you capitalized mom in this sentence and put a name then it wouldn't make sense because the word my was added. Hopefully this helps and makes sense. Good luck!!!
