Plain form vs keigo

Plain form is the basic form of a verb or adjective in Japanese. It's called "plain" because it's the simplest and most straightforward form, without any added politeness or formality. Plain form is used in informal situations, such as talking to friends, family, or people of lower status.

Keigo, on the other hand, is a set of honorific language expressions used to show respect, politeness, and formality in Japanese.

In general, plain form is used in informal situations and keigo is used in formal situations. However, it's important to note that there are different levels of keigo depending on the level of formality and the relationship between the speaker and listener. For example, the keigo used with a superior in a workplace setting might be different from the keigo used with a customer or client.

It's also worth noting that keigo can be difficult to master, even for native Japanese speakers. There are many different honorific expressions and rules for using them correctly, so it's important to study and practice them carefully in order to use them effectively.

Not every form above has a distinct keigo equivalent: the conditional, provisional conditional, causative, and potential forms aren't typically expressed differently in polite speech, so only forms with their own recognized keigo pattern are shown in the Keigo column.
