ます

参(まゐ)らす (mairasu) → まらす (marasu) → まっす (massu) → ます (masu)

The -ます ending is generally believed to have come from the Old Japanese auxiliary verb 参(まゐ)らす (mairasu, “to humbly do something for a superior”), with idiomatic use arising from the causative conjugation of 参る (mairu, “to come or go to the place of a social superior”, humble verb; ancient reading mawiru).^[1][2]

The intermediate forms まらす (marasu) and まっす (massu) were valid as both 下(しも)二(に)段(だん)活(かつ)用(よう) (shimo nidan katsuyō) conjugations and サ行(ぎょう)変(へん)格(かく)活(かつ)用(よう) (sa-gyō henkaku katsuyō) conjugations, even though they originally came from a purely 下(しも)二(に)段(だん)活(かつ)用(よう) (shimo nidan katsuyō) conjugation, leading to constructions off the 連(れん)用(よう)形(けい) (ren'yōkei) in the modern paradigm for -ます using the -まし stem.

• (Tokyo) ます [máꜜsù] (Atamadaka – [1])
• IPA^(key): [ma̠sɨ̥]

• In Tokyo speech, the accent falls somewhere in the suffix, regardless of the accent type of the suffixed verb:^[3]
  • If the suffix is in the form ます (-masu) or ました (-mashita, past/perfective form), the accent of the verb construction falls on the first mora of the suffix.
  • If the suffix is in the form ましょう (-mashō, volitional/conjectural form) or ません (-masen, negative form), the accent of the verb construction falls on the second mora of the suffix.
• There are a few exceptions like 恐れ入る: おそ​れいる [òsóꜜrèìrù] (Nakadaka) → おそ​れいります [òsóꜜrèìrìmàsù] (Nakadaka).
