How to form it

Put も after the noun it adds: 私(わたし)も学生(がくせい)です (I'm a student too).
も replaces は, が and を. Other particles stay, and も goes after them: 東京(とうきょう)にも行(い)きました (I went to Tokyo too).
Two も mean "both" in a positive sentence and "neither" in a negative one: 肉(にく)も魚(さかな)も食(た)べます (I eat both meat and fish), 肉(にく)も魚(さかな)も食(た)べません (I eat neither).

私(わたし)も学生(がくせい)です。

I'm a student too.

コーヒーも飲(の)みます。

I drink coffee too.

After a number, も stresses how much: 三時間(さんじかん)も待(ま)った (I waited a whole three hours).
After a question word with a negative, も means "no-": see 疑問詞(ぎもんし)+も + negative.
