V-ば（食べる→食べれば、行く→行けば、する→すれば）／Aい→Aければ（高い→高ければ）／Aな・N→なら（ば）（でなければ）
Explanation
The ば conditional states that if the first clause holds, the second naturally follows. It often expresses a general truth, a natural consequence, or advice. Verbs change the final -u to -e plus ば; い-adjectives replace い with ければ.
Examples
Note
When the main clause is a request, command, or invitation, ば is often avoided (use たら instead). With verbs, ば leans toward general/hypothetical conditions rather than one specific past-like event.
