Spoken Japanese conjugation FAQ
Why do Japanese subtitles use てる instead of ている?
In casual speech, the い in ている or でいる is frequently omitted. 食べている becomes 食べてる, and 読んでいる becomes 読んでる.
How do I know whether a る verb is ichidan or godan?
The ending alone is not always enough. Many verbs are ichidan, but common verbs such as 帰る and 走る are godan. Use a dictionary when the suggestion is uncertain.
What do ちゃう, じゃう, and なきゃ mean?
ちゃう contracts てしまう, じゃう contracts でしまう, and なきゃ is a casual shortening of an obligation pattern such as なければならない.
