普通形／じしょ形 (Futsuu Kei / Jisho Kei)


Are 普通形 and 辞書形 different? If so, how do they differ? I would appreciate an
example.




I am not 100% sure but I would guess that what you refer to as 普通形 is what in
English is often translated as "casual" or "standard" conjugation as opposed
to 丁寧形{ていねいけい} that is the "polite" form instead. [This

to prove me right.

On the other hand, 辞書形｛じしょけい｝ is the so-called dictionary form and it's called
this way because it is the form in which the verb is found in dictionaries.

To give a concrete example:

Verb: 買う｛かう｝- to buy

**普通形** : 買う (positive and non past. In this case this is the same as the
dictionary form), 買わない (negative-non past), 買った (positive-past), 買わなかった
(negative-past).

**丁寧形** : 買います (positive-non past), 買いません (negative-non past), 買いました
(positive-past), 買いませんでした (negative-past).

**辞書形** : It's just 買う. This is how you find the verb "to buy" in any
dictionary. You can see it as a non-conjugated basic form as it could be the
infinitive in English (in dictionaries you find "buy", not "bought" for
example).
