This page is a hub for the hypothetical form 仮定形. It describes how to conjugate verbs and adjectives to their hypothetical form. The hypothetical form is a kind of stem form of both kinds of word, which can be used to compose a conditional form by appending ば.
形容動詞 and nouns
Append であれば to the adjective.
- この町は今日賑やかであれば、田舎に行きましょうか。
- If this town is busy today, shall we go to the countryside?
The ある here is actually the inanimate existence verb. So a literal meaning could be if there is busyness.
形容詞
Drop the い (from the attributive form) and append けれ.
- 映画は面白ければ、また見ます。
- If the film is interesting I'll watch it again.
一段 verbs
Replace the trailing る with れば.
- このキノコを食べれば、背が高くなります。
- If you eat this mushroom, you'll become taller.
五段 verbs
Modify the last sound to the e ending sound from the same row of the kana table.
- また日本人の友達に会えば幸せになります。
- If I meet my Japanese friends again, I will be happy.
