1. What is Conditional Form?

The conditional form in Japanese is a verb form that expresses a condition or hypothesis. It is often used to construct conditional sentences, conveying meanings like "if..." or "when...".

2. Construction of Conditional Form

The construction of the conditional form varies depending on the type of verb. Below are the rules for forming the conditional form for the three verb categories.

2.1 Group 1 Verbs (Godan Verbs)

For Group 1 verbs, the conditional form is created by changing the final sound to its corresponding "e-sound" and adding "ば".

2.2 Group 2 Verbs (Ichidan Verbs)

For Group 2 verbs, the conditional form is formed by dropping "る" and adding "れば".

2.3 Irregular Verbs

The conditional forms of irregular verbs are straightforward.
