丁重語 details

Examples

courteous speech — the formal version of an everyday verb, used about yourself where there is nobody in particular to defer to

それでは、私わたしが先さきに参まいります。

soredewa, watashi ga saki ni mairimasu.

In that case, I will go on ahead. formal

母ははは今いま、出でかけております。

haha wa ima, dekakete orimasu.

My mother is out at the moment. formal

初はじめまして、田中たなかと申もうします。

hajimemashite, tanaka to moushimasu.

How do you do — my name is Tanaka. formal

その件けんについては、まだ何なにも存ぞんじておりません。

sono ken ni tsuite wa, mada nani mo zonjite orimasen.

I don't know anything about that matter yet. formal

ございます belongs to a third register, 丁寧語ていねいご: it polishes
です・あります for the listener (二階にかいでございます) and says nothing
about whose action it is.

尊敬語
丁重語 raises nobody inside the sentence — it lifts the tone toward whoever is listening — while 尊敬語 raises a person named in it; so 参まいります needs no esteemed destination and stands equally in 駅えきに参まいります and 田舎いなかに参まいります.

謙譲語
申もうし上あげる and 申もうす differ by more than length — 謙譲語 needs someone the action reaches and lowers you toward them (先生せんせいに申もうし上あげる), while 丁重語 has no such person and merely dresses the act for the listener (私わたしは田中たなかと申もうします).

お〜する
いたす is what する becomes when the humble wrap goes up a notch — お届とどけいたします; the wrap stays お〜, so this register is a swap inside it rather than a frame of its own.
