The -aru Honorifics: Special 〜います Stems

Japanese has a tiny, closed club of five honorific verbs that all end in -る and all break the same rule the same way: いらっしゃる, おっしゃる, くださる, なさる, ござる. Everywhere else they conjugate like ordinary 五段 -る verbs, but at the polite form the り-row stem drops its り and softens to -い-, producing 〜います instead of the regular ×〜ります. Learn the shift once and it unlocks all five at a stroke. This page is the shared-morphology overview; each verb has its own full paradigm linked below, and the usage (whom you may elevate, when) lives in the 尊敬語 (sonkeigo) pages.

The five verbs and their irregular ます-forms

DictionaryMeaning (honorific of…)Polite ます-formNOT
いらっしゃるbe / come / go (いる・来る・行く)いらっしゃいます×いらっしゃります
おっしゃるsay (言う)おっしゃいます×おっしゃります
くださるgive to me (くれる)くださいます×くださります
なさるdo (する)なさいます×なさります
ござるbe / exist (ある, 丁寧語)ございます×ござります

The pattern is mechanical: take the ら-row dictionary form, and where a normal 五段 verb would give ~り+ます, these give ~い+ます. なさる → なさます; くださる → くださます. Nothing else about them is unusual.

社長は毎朝ジョギングをなさいます。

shachō wa maiasa jogingu o nasaimasu

The company president goes jogging every morning. (なさる → なさいます)

部長は何とおっしゃいましたか。

buchō wa nan to osshaimashita ka

What did the department head say? (おっしゃる → おっしゃいました)

ご不明な点がございましたら、お問い合わせください。

go-fumei na ten ga gozaimashitara, o-toiawase kudasai

If anything is unclear, please contact us. (ござる → ございます)

The anchor: くださる → くださいます

Take くださる ("to give to me," honorific of くれる) as your reference verb, because you meet it constantly inside 〜てくださる ("do a favor for me"). Its polite form is the irregular くださます; everything else is regular 五段.

FormくださるReading

Polite ますくださいますkudasaimasu
Te-form (regular)くださってkudasatte
Past (regular)くださったkudasatta
Plain negative (regular)くださらないkudasaranai
Imperativeくださいkudasai

Note the last row: the everyday ください in 〜てください is this verb's imperative, and it too uses the -い- stem (くださ), not a regular 五段 ×くだされ. That is the second half of the rule — the -い- stem is obligatory before ます and in the imperative.

先生がいつも励ましてくださいます。

sensei ga itsumo hagemashite kudasaimasu

My teacher always encourages me.

わざわざ来てくださって、ありがとうございます。

wazawaza kite kudasatte, arigatō gozaimasu

Thank you so much for coming all this way. (regular te-form くださって)

The -い- stem also carries the imperative

Every one of the five (except ござる, which has no everyday imperative) makes its command on the same -い- stem: くださ, なさ, いらっしゃ, おっしゃ. This is why so many high-frequency polite forms end in -い:

VerbImperative (-い stem)Where you meet it
くださるください〜てください "please do…"
なさるなさい〜なさい, a firm "do…" to a child/student
いらっしゃるいらっしゃい(ませ)いらっしゃいませ "welcome" (shops)
おっしゃるおっしゃいrare/theatrical "go on, say it"

宿題は毎日ちゃんとしなさい。

shukudai wa mainichi chanto shinasai

Do your homework properly every day. (なさい, said to a child)

どうぞ、こちらにいらっしゃい。

dōzo, kochira ni irasshai

Come this way, please. (いらっしゃい)

Why it works this way

The -い- is a fossilized イ音便 (イおんびん) — a euphonic softening of the ら-row that this closed honorific class froze into place centuries ago, before ます and the imperative suffix. There is no live rule generating it and no way to predict which verbs belong: the membership is exactly these five, all originating as court/honorific vocabulary. So treat them the way you treat any short irregular set in a language — as a memorized list, drilled together.

💡
Bind the five as one chant: いらっしゃます・おっしゃます・くださます・なさます・ございます. The instant your mouth wants to say ×なさます, the chant catches it. One drill fixes all five.

Register notes and where each verb lives

Four of the five are 尊敬語 (you raise someone else with them); ござる is 丁寧語, a plain politeness marker with no "elevate the subject" function.

The one-glance comparison of all five (plus their humble counterparts) is on the suppletive honorific verbs table.

お客様はもうお帰りになりましたか。いいえ、まだいらっしゃいます。

o-kyakusama wa mō o-kaeri ni narimashita ka. iie, mada irasshaimasu

Has the customer already left? No, they're still here.

何かご希望があれば、遠慮なくおっしゃってください。

nanika go-kibō ga areba, enryo naku osshatte kudasai

If you have any requests, please don't hesitate to tell me.

ございます wears two hats

ございます is the odd one out in the set: it is not 尊敬語 but 丁寧語 (plain politeness), and it does two different jobs that beginners blur together.

  • Existence — the polite ある: あります → ございます ("there is / we have"). This is the shop-and-signage register.
  • Copula — the polite です: です → でございます ("is / it is"), the で of the copula plus ございます.

お手洗いは二階にございます。

o-tearai wa nikai ni gozaimasu

The restroom is on the second floor. (existence = polite ある)

はい、こちらが受付でございます。

hai, kochira ga uketsuke de gozaimasu

Yes, this is the reception desk. (copula = polite です)

Both come from the same verb ござる, and both take the identical -い- stem in ございます / ございません / ございました. The negative existence ございません ("there isn't") is the most deferential way to say ない — the full treatment is on でございます.

How this differs from English

English has no productive politeness conjugation — you show respect with word choice and modal softening ("would you," "could you"), never by re-inflecting the verb. Japanese lexicalizes it: these five verbs are the polite versions of する, 言う, いる/来る/行く, くれる, and ある, and they carry a frozen sound change an English speaker has no template for. The reflex to avoid is the "regularizing" one — hearing an -る verb and forcing the normal 五段 ×〜ります. That instinct is right for 取る and wrong for exactly these five.

Common mistakes

❌ 部長がそうおっしゃりました。

Incorrect — the polite form softens り to い: おっしゃいました.

✅ 部長がそうおっしゃいました。

buchō ga sō osshaimashita

The department head said so.

❌ 社長は何をなさりますか。

Incorrect — なさる → なさいます, never ×なさります.

✅ 社長は何をなさいますか。

shachō wa nani o nasaimasu ka

What will the president do?

❌ 資料を送ってくだされ。

Incorrect — ×くだされ is an archaic (period-drama) imperative; the modern imperative is ください.

✅ 資料を送ってください。

shiryō o okutte kudasai

Please send the materials.

❌ ありがとうござります。

Incorrect — ×ござります is the old Meiji-era form; modern polite is ございます.

✅ ありがとうございます。

arigatō gozaimasu

Thank you.

Key takeaways

  • Five -る honorifics share one quirk: the polite form is 〜います, not ×〜ります — いらっしゃいます・おっしゃいます・くださいます・なさいます・ございます.
  • The -い- stem also carries the imperative: ください, なさい, いらっしゃい — not regular 五段 ×くだされ/×なされ.
  • Everything else about them is regular 五段: te-form くださって, past なさった, negative おっしゃらない.
  • The shift is a fossilized イ音便 in a closed class — memorize the five as a set; you cannot predict membership.
  • ござる is archaic except for ございます / でございます; the other four are living 尊敬語.
