Add something to what has just been said.
The rule
も often means "also". In a negative sentence, it can be "neither". It frequently replaces は or が.
Examples
わたしもいきます。
I'm going too.
きょうもいきません。
Today, too, I'm not going.
Remember
- も often replaces は or が when it adds "also".
- Add something to what has just been said.
Common mistake
Avoid juxtaposing はも in this context: say わたしも.
