When would you use 敬語 in its plain forms?


Are there any examples of people using verbs such as いただく, 参る, 申す, いたす (and
their 尊敬語 counterparts, along with the various other humble/respectful verbs)
in those plain forms, rather than conjugated as 丁寧語? I also mean at the end of
a sentence, rather than as part of a larger clause that requires dictionary
forms.




丁寧語 is about who you are talking to. Its use is to be polite to your
listener/reader.

尊敬語/謙譲語 are about who you are talking about. These patterns show respect to
the agent. 謙譲語 to lower yourself (or someone on the same side as you vis-a-vis
your listener) and 尊敬語 to raise the person you're talking about.

Thus, you can say

> 先生からみかんをいただいた。

or

> 先生が私にりんごをくださった。

when speaking to a friend to simultaneously respect the teacher and
communicate casually with a friend.

To kind of complete the pattern,

> 友達から鉛筆をもらいました。

makes sense to say to a teacher about something that happened with a peer.

I can't imagine when you could say 申す at the end by itself considering for its
meaning...
