みんな も — Tae Kim's Japanese Grammar flashcard

今日きょう は ありがとう

Note the long pronunciation of the "o"s.
They result from yo/よ + u/う and to/と + u/う in this case.

今日きょう は ごめん

僕ぼく も

私わたし も

今日きょう も

Pay attention to the intonation: We have a question here (without question marker).
Note the long o, which results from yo + u

私わたし も  行いく
