which group a verb belongs to in order to produce theconjugated forms.
Grouping rules:
Group 1:
Verbs in group 1 end with the syllable ru (), with the
preceding syllable containing the vowels e or i . Someexceptions are kaeru ( "return home"), hashi ru (
"run"), ki ru ( "cut"), i ru (, "need"), and hai ru (
"enter").
Group 2:
Verbs in group 2 end with
syllables k u (), g u (), su (), mu (), nu (), bu (), u(), t su (), or ru (). Verbs ending in ru () contain the
vowels u, o or a in the preceding syllable. Some exceptions
are kaeru ( "return home"), hashi ru (
"run"), ki ru ( "cut"), i ru (, "need"), and hai ru (
"enter").
Group 3:
