17 meanings of hum

Practice

  1. 1
    verbintransitive
    To make a wordless musical sound with the vocal cords while keeping the lips closed.

    I hum along whenever that old song comes on the radio.

    The toddler hummed quietly until she fell asleep.

    Note

    At its core the verb takes no object: someone simply hums, and whatever follows is a phrase, as in hum along, hum along with the music, or hum happily. Put a tune directly after the verb and it shifts to its transitive use, where the melody is the thing hummed. In both uses the lips stay closed, and that is what separates humming from singing.

  2. 2
    nouncountable
    A faint, often unclear sound that resembles a person humming.

    A steady hum filled the room from the overhead lights.

    The hum of distant traffic drifted through the open window.

    Similardrone, buzz, murmur, whir, thrum

    Note

    Here the hum belongs to things rather than people: a dishwasher left running, overhead lights, an insect in flight. Shakespeare gives the beetle in Macbeth (c. 1606) its "drowsy hums," a plural that counts each drone as its own sound. Everyday English tends to keep the word singular and name the source with of, as in the hum of traffic. The verb behind the insect image is to drone like a flying insect.

  3. 3
    interjection
    A sound used to show that the speaker is thinking over or considering something.

    Hum, I hadn't considered that possibility before now.

    Hum, perhaps we should look at the figures again.

    Similarhmm

    Note

    A written thinking-noise with a long history: Arthur Conan Doyle's The Sign of Four (1890) has "Hum! hum! What's all this?" It does the work of hmm, and the doubled, exclaimed form shows someone puzzling over what is in front of them. As a single word set off by a comma, it gives a sentence a considering pause before the real thought arrives.

  4. 4
    verbintransitive
    To make a low, continuous droning sound, like the noise flying insects make in motion.

    Mosquitoes hum near your ear just as you're falling asleep.

    The old machine hummed steadily in the corner of the workshop.

    Similarbuzz, drone, whir, whine, purr

    Note

    Insects are the model here, and writers have favored the bee. Alexander Dow's 1769 translation has "the humming bee, drunk with joy", and Virginia Woolf's Jacob's Room (1922) has "a bee humming at the yellow flower". The participle sits comfortably before a noun, and the verb takes at for whatever the insect hovers over.

  5. 5
    nouncountable
    A tune produced with the lips closed rather than sung with words.

    A cheerful hum escaped her as she stirred the soup.

    He recognized the tune from just a few notes of her hum.

    Note

    The tune-sense sits closest to the word's sound: Middle English hummen, probably imitative, with kin in Dutch hommelen "to bumble, buzz." Middle English hummen could also mean a murmur made to cover embarrassment, a use that echoes in the hesitant "um". You hum a song, and what comes out is a hum. The shellfish hum, meaning blood cockles, is a separate word borrowed from Hokkien.

  6. 6
    verbintransitive
    To produce low sounds that blend together in a continuous stream.

    Generators hum through the night at the construction site.

    The city's traffic hummed in the distance as dusk fell.

    Similardrone, rumble, murmur, purr, whir

  7. 7
    verbtransitive
    To convey a tune or feeling by humming rather than speaking or singing it.

    She hummed a few bars of the melody to remind us.

    Drivers often hum tunes to stay alert on long trips.

  8. 8
    nouncountable
    Lively, busy activity in a place, resembling the buzz of a beehive.

    The office had a constant hum of activity before the deadline.

    A cheerful hum filled the kitchen as the family prepared dinner.

    Similarbuzz, bustle

  9. 9
    verbintransitive
    To be busily active and full of energy, like a buzzing beehive.

    Trading floors hum with activity the moment the market opens.

    The fairgrounds hummed with life all weekend long.

    Similarbuzz, bustle, teem, throb, pulse

    Note

    The figurative use takes with: a street or an office hums with activity, life or energy. The image comes from the beehive, with sound standing in for busyness, and the progressive is natural, as in the streets were humming. The noun for busy activity carries the same picture in a hum of activity.

  10. 10
    interjection
    A sound used to signal doubt, hesitation, or uncertainty.

    Hum, I suppose we could try it your way, though I have my doubts.

    When asked for a decision, all he managed was a noncommittal hum.

    Similarum

    Note

    Where the thinking noise marks consideration, this one marks a stumble, and it sits in the middle of a sentence the way um does. Stephen Fry's The Liar (1991) uses it just before a delicate phrase: "They were both, hum, 'put out' themselves." Set off by commas, it shows a speaker hesitating over a word rather than over a decision.
