お／ご Attachment Errors | Japanese Grammar

The polite prefixes お and ご feel like free garnish — sprinkle one on a noun and the sentence gets more polite, right? That intuition produces a steady stream of errors: ×お住所, ×ご名前, ×おコーヒー, ×私のお名前, ×お社長. The truth is that お／ご is governed by three independent filters, and a word has to clear all three before the prefix is licensed. First, the word's reading decides which prefix (native 和語 → お, Sino 漢語 → ご). Second, the possessor decides whether an honorific prefix belongs at all (someone else's thing → keep it, your own thing → drop it). Third, the word-class can veto it outright (loanwords and job titles reject it). "It sounds more polite" passes none of these checks by itself. Run all three, every time.

The three filters at a glance

Filter	Question	Verdict
Reading	Is the word native (和語) or Sino (漢語)?	和語 → お; 漢語 → ご
Possessor	Whose thing is it — theirs or mine?	theirs → keep honorific prefix; mine → drop it
Word-class	Is it a loanword, a title, or an ordinary noun?	loanwords & titles → no prefix

Filter 1 is the subject of its own page, お vs ご: 和語 vs 漢語 Selection — here we focus on the errors each filter catches, and especially on filters 2 and 3, which trip up even learners who have the reading rule down.

Filter 1 — reading: お for 和語, ご for 漢語

The prefix is fixed by the word's etymological layer, not its meaning. 名前 (namae) is a native word, so it takes お; 住所 (jūsho) is a two-kanji Chinese loan, so it takes ご. You cannot ask a customer "your name and address" and put the same prefix on both — the pair splits.

お名前とご住所をご記入ください。

o-namae to go-jūsho o go-kinyū kudasai

Please write your name and address.

Get the layer backwards and you produce the two commonest prefix errors. お on a Sino word:

❌ お住所を教えてください。

Wrong prefix — 住所 (jūsho) is Sino, so it takes ご, not お: ご住所.

✅ ご住所を教えてください。

go-jūsho o oshiete kudasai

Please tell me your address.

And ご on a native word:

❌ ご名前をフルネームでお書きください。

Wrong prefix — 名前 (namae) is native, so it takes お: お名前.

✅ お名前をフルネームでお書きください。

o-namae o furunēmu de o-kaki kudasai

Please write your full name.

💡

The prefix follows the reading, not the meaning: お rides with kun-reading 和語, ご with on-reading 漢語. When two personal-info words sit side by side — お名前・ご住所, お電話・ご連絡 — the prefix often flips between them. For the full list of exceptions (the 漢語 that keep お, like お電話・お食事), see the 和語 vs 漢語 page.

Filter 2 — possessor: don't honour your own things

This is the filter English speakers most often miss. An honorific お／ご on a noun says "this thing belongs to a person I respect." So attaching it to your own name, opinion, or belongings honours yourself — a self-contradiction that lands as either arrogant or simply confused. When the thing is yours, drop the prefix.

❌ 私のお名前は田中と申します。

Self-honouring — you can't put an honorific お on your OWN name. Drop it (and just 田中と申します is cleanest).

✅ 私は田中と申します。

watashi wa tanaka to mōshimasu

My name is Tanaka.

❌ 私のお考えを申し上げます。

Self-honouring — お on your own 考え elevates yourself. Drop it: 私の考え.

✅ 私の考えを申し上げます。

watashi no kangae o mōshiagemasu

I'll share my thoughts.

The same noun swings with the possessor. Your teacher's opinion is ご意見; your own is just 意見. Your teacher's letter is お手紙; the one you send is 手紙 (or the humble お手紙 only in the frozen politeness of set business phrases). The prefix is a little arrow pointing at the owner.

先生のご意見を伺いたいのですが、私の意見も少しお話しします。

sensei no go-iken o ukagaitai no desu ga, watashi no iken mo sukoshi o-hanashi shimasu

I'd like to hear your opinion, sensei, but let me also say a little about mine.

The 美化語 exception — words that beautify without honouring anyone

One honest caveat, or the possessor rule would mislead you. A set of お-words are not honorifics at all but 美化語 (bikago, "beautification") — lexicalised soft vocabulary where the お has fused into the word and points at nobody. お茶, お金, ご飯, お水 — these stay お even about your own, because they are not marking a possessor's status; they are just the polished everyday form of the word.

私はいつも朝にお茶を飲みます。

watashi wa itsumo asa ni o-cha o nomimasu

I always drink tea in the morning.

So 私のお名前 is wrong (honorific お misapplied to your own name) but 私はお茶を飲む is perfectly fine (beautifying お, no possessor honoured). The test: if removing お changes whose thing it is (お名前 → someone's name vs. 名前 → a name), it is honorific and drops for yourself; if removing お just makes the word blunter (お茶 → 茶), it is 美化語 and stays. This layer gets its own treatment on the 美化語 page.

Filter 3 — word-class: loanwords and titles reject the prefix

Even a word that clears filters 1 and 2 can be blocked by what kind of word it is.

Loanwords (katakana) take neither prefix. Modern borrowings live in a third etymological layer (外来語), and the polite prefixes simply do not attach to them in standard speech. ×おビール, ×おコーヒー, ×おタクシー all sound wrong (a few, like おビール, survive as jokey or hyper-service usage, but they are non-standard).

❌ おコーヒーをお持ちしましょうか。

Loanword — katakana コーヒー rejects お in standard speech. Plain コーヒー.

✅ コーヒーをお持ちしましょうか。

kōhī o o-mochi shimashō ka

Shall I bring you a coffee?

Job titles don't take お either. A title like 社長, 部長, or 先生 is already deferential — the title itself does the honouring — so you never prefix it with お. To dress it up further you add 様 (社長様) in very formal writing, but ×お社長 is not Japanese.

❌ お社長はただいま外出しております。

Titles are already honorific — 社長 takes no お. Say 社長 (or 社長様 in very formal writing).

✅ 社長はただいま外出しております。

shachō wa tadaima gaishutsu shite orimasu

The president is out at the moment.

💡

Before you attach お／ご, clear all three gates: (1) native → お, Sino → ご; (2) someone else's thing → keep it, your own → drop it; (3) loanword or job title → no prefix at all. "It sounds politer" is not a licence — it fails every gate on its own.

Common mistakes

Mistake 1 — お on a Sino word. English speakers latch onto お (it comes first and looks simpler) and put it on everything.

❌ お住所をご記入ください。

Wrong prefix — 住所 is Sino (jūsho), so ご住所.

✅ ご住所をご記入ください。

go-jūsho o go-kinyū kudasai

Please fill in your address.

Mistake 2 — ご on a native word. Overcorrecting the other way, learners put ご on native nouns like 名前.

❌ ご名前をお願いします。

Wrong prefix — 名前 is native (namae), so お名前.

✅ お名前をお願いします。

o-namae o o-negai shimasu

Your name, please.

Mistake 3 — Honouring your own thing. The self-reference trap: お／ご on your own name, opinion, or address.

❌ 私のお名前と、お住所をお伝えします。

Self-honouring — drop the honorific prefixes from your OWN details: 私の名前と住所.

✅ 私の名前と住所をお伝えします。

watashi no namae to jūsho o o-tsutae shimasu

I'll give you my name and address.

Mistake 4 — Prefixing a loanword. Adding お to a katakana word to "sound polite."

❌ おビールをお注ぎします。

Loanword — katakana ビール takes no prefix in standard speech. Plain ビール.

✅ ビールをお注ぎします。

bīru o o-tsugi shimasu

Let me pour you some beer.

Mistake 5 — Prefixing a title. Treating 社長／部長／先生 as if they needed お to be respectful.

❌ お部長にお伝えください。

Titles are already honorific — 部長 takes no お. Say 部長にお伝えください.

✅ 部長にお伝えください。

buchō ni o-tsutae kudasai

Please pass this on to the chief.

Key takeaways

お／ご is not free garnish — it must clear three independent filters before it is licensed.
Filter 1 (reading): native 和語 → お, Sino 漢語 → ご. Reversing it gives ×お住所 / ×ご名前.
Filter 2 (possessor): an honorific prefix marks someone else's thing — drop it from your own (×私のお名前, ×私のお考え). But lexicalised 美化語 (お茶, お金, ご飯) stays, because it honours no one.
Filter 3 (word-class): loanwords (×おコーヒー) and job titles (×お社長) reject the prefix entirely.
"It sounds more polite" licenses nothing by itself. For the reading rule in full, see お vs ご: 和語 vs 漢語 Selection; for the beautification layer, 美化語: お／ご Beautification.
