また
Use また if you want to say ‘Also’ at the start of an English sentence.
Also, I sometimes study Japanese.
また、私はときどき日本語を勉強します。

も

Whereas, if you would like to say ‘I speak (not only English but also) Japanese.’
then, 私は日本語も話します。is correct in Japanese.

With the sentence above,
you would like to say ‘(Not only my mother but also) my father is good at tennis.’
then, 父もテニスが上手です。is correct in Japanese.
