Note
The declamatory use belongs to poetry and to the rolling prose of earlier centuries. In the preface to The Historie of the World (1614), Walter Raleigh writes "Oh, by what plots…", and Lawrence Smith has "oh how stingingly acute." In everyday speech the same move sounds deliberately theatrical.

7
interjection
A word used to call out to or address someone directly, often before a name or a term of endearment.
Oh, my love, how I have missed your gentle voice.
Oh, children, gather round and hear this old story.
UsageOlder texts and hymns often use O for direct address: O Lord.
Note
Here the word does the job a case ending does in languages that decline their nouns: instead of marking the person addressed on the noun itself, English places a word in front of it. It most often leads into a term of endearment, and in song the comma can vanish. The 1998 Max Martin lyric sung by Britney Spears runs straight on into a repeated endearment, with no comma after the word.
8
interjection
A word used to mark a following phrase as imagined or hypothetical speech.
They always claim, oh, we never received the message.
You expect him to admit, oh, I was completely wrong?
UsageUsually right after a verb of saying: they'll say, oh, we're busy.
Note
Here oh belongs mainly to a voice the speaker is putting on, not to the speaker. It opens words imagined in someone else's mouth, as in What if she says "Oh, we're fully booked"? Unlike the surprised oh, it need not show any reaction. Chiefly it signals that the words to come are made up.
9
skepticalinterjectioninterrogative
A word used to express mild skepticism or doubt about what was said.
Oh, is that so? I'd want to see proof first.
Oh, you finished the whole project in one night? Right.
UsageOften said with rising intonation, either alone (Oh?) or before a question (Oh, really?).
Note
A one-word question, said on its own and written with a question mark, invites the other speaker to back up what they just claimed. The reply "Oh?" to "I could beat you at chess any day." is cool rather than startled. That standalone, questioning form is what separates it from the cry of surprise, which usually takes an exclamation mark or runs on into more words.
10
nouncountable
A spoken utterance of oh, expressing surprise, acknowledgment, or a similar feeling.
The audience let out a string of delighted ohs as each new costume appeared on stage.
Her quiet oh told me she had finally understood.
UsagePlural ohs, often in ohs and ahs from a crowd.
Note
It is most at home in crowds and in pairs. "There were ohs and ahs," writes Seabert Parsons in The Lost Codex of Palenque (2011). That stock phrase describes an audience's collective murmur of surprise or admiration.

zeronouncountable
The digit zero, especially as spoken aloud in sequences of numbers.
The agent's code name was double oh seven.
According to the deed, the farmhouse was built in nineteen oh five.
Similarzero, nought
Note
Speakers borrow the round letter to say the round digit, so this use comes from reading 0 as the letter name. It belongs to strings read out digit by digit, such as telephone numbers, decimals (point oh eight) and clock times.
Checked 31 Oct 2026 · 1 fact

12
paininterjection
A word used to express a sudden feeling of pain.
Oh, my knee! I just banged it hard on the table leg.
Oh! That needle stung more than I expected.
UsageFor sudden pain, ouch is the more usual word: Ouch, that hurts!
Similarouch, ow
Note
Pain draws out the bare cry, usually punctuated with an exclamation mark. The line between agony and its opposite can be thin, though. In Fanny Hill, John Cleland gives "Oh! . . . oh! . . . I can't bear it" as a character's cries of ecstasy. Context, not the word itself, tells the reader which feeling is meant.

13
song fillerinterjection
A sound used as a filler or extra syllable, especially in popular music.
The bridge fills the empty bars with a drawn-out oh.
Backing vocals chant oh, oh behind the lead singer.
Note
Song uses it for sound rather than sense, to stretch a line to fit the tune. It can even attach to the end of a word with a hyphen, as in "the raggle-taggle gypsy-oh," quoted by MacKinlay Kantor in Beauty Beast (1968). There the extra syllable carries the melody without adding any meaning at all.

letter namenouncountable
The spoken name of the letter O in the Latin alphabet.

He read each letter clearly, ending with a long oh.
Note
This is a separate word from the exclamation, though spelled the same. It came through Middle and Old English from the Latin name of the letter. It is how the letter is said when a formula is read aloud: Ben Bova's Titan (2006) renders water as "aitch-two-oh." It also invites puns, as in Shallon Lester's 2011 title Exes and Ohs.
