What you can solve

How to conjugate japanese verbs?

Verbs ending in 'eru' or 'iru' are usually Ichidan verbs (like 食べる). However, '帰る' (to return) is a famous exception—it is a Godan verb. If the 'Auto-Detect' gets confused by an exception, simply click 'Godan' manually to fix the conjugation.

Te form of iku?

The dictionary form (辞書形) is the base, casual form of a verb as it appears in a dictionary. It always ends in an 'u' vowel sound (e.g., 食べる - taberU, 飲む - nomU, 行く - ikU).
