This section deals only with Japanese as written and spoken in 21st and late 20th centuries.

Stem forms
These are the basic forms of verbs as taught in Japan. Verbs have six associated stem forms; three of these each appear in two different ways that are not given separate names, but are used in disjoint contexts. The izenkei 已然形 (classical imperfective form) is also called the kateikei 仮定形 (hypothetical form). The shūshikei 終止形 (terminal form) and rentaikei 連体形 (attributive form) are identical for verbs in modern Japanese.

The ren'yōkei 連用形 (-i form), shūshikei 終止形 (terminal), rentaikei 連体形 (attributive), and meireikei 命令形 (imperative) forms can appear on their own; the others require suffixes.
