Practice

  1. 1
    nouncountable
    A device that slows or stops the motion of a wheel or vehicle, usually by friction; also the controls used to engage it, such as a car's pedal.

    He slammed on the brake when the light turned red.

    The mechanic replaced the worn brakes before the long trip.

    Note

    The everyday sense, the one a driver means. Its origin is uncertain: it may come from Middle Dutch or Middle Low German brake, meaning a nose ring, a curb or a flax brake, from a Germanic root meaning "to break." In speech the plural dominates, so you slam the brakes or press the brakes. Spelling is all that separates it from break, which sounds identical.

  2. 2
    verbintransitive
    To operate a brake or brakes in order to slow down or stop.

    The driver braked hard to avoid the cyclist.

    Always brake before entering a sharp turn.

    Similarslow, decelerate, stop

    Oppositeaccelerate

    Note

    The verb is regular, and that is where writers slip: the past is braked and the present participle is braking. Because brake and break sound alike, it is easy to write broke where braked is meant. The driver braked; the window broke. The old past tense brake belongs to break, not to this verb; see the archaic past of break.

  3. 3
    nouncountable
    The action of applying a brake to slow down a machine or vehicle.

    A gentle brake brought the train smoothly into the station.

    Her sudden brake left skid marks on the road.

  4. 4
    nounfigurativelycountable
    Anything that serves to slow down or stop an action, process, or trend.

    Rising interest rates put a brake on the housing market.

    Bureaucracy often acts as a brake on innovation.

    Similarcurb, check, restraint, damper, drag

    Oppositespur, stimulus, boost

    Note

    The machine turned into metaphor: whatever holds back a process can be called a brake on it, whether the process is spending, growth or reform. The usual construction is a brake on something. Keep the spelling straight, because the sound invites a slip. A break in a process is a pause or a rupture, while a brake on it is a restraint that slows it.

  5. 5
    verbintransitive
    To slow down or come to a stop as though a brake had been applied.

    The runaway trolley finally braked against the sandy embankment.

    Spacecraft brake using the friction of the atmosphere.

    Similarslow, decelerate, stop, halt

    Oppositeaccelerate

    Note

    Here the subject is the thing that slows, not a person working a pedal. With the operating verb, a driver brakes. In this use a trolley, a spacecraft or anything else in motion brakes by itself. The "as if" allows the slowing force to be something other than a brake at all, such as sand, air or friction.

  6. 6
    nouncountable or uncountable
    A large, coarse fern (Pteridium species), commonly known as bracken, that grows in open ground and woodland.

    Sheep grazed near the brake on the open moor.

    By late summer the brake had turned brown and brittle.

    Similarbracken

    Note

    Here the clipped word returns to the plant it was clipped from: bracken, of the genus Pteridium. Botanists keep Pteridium apart from Pteris, the genus covered by the Pteris fern, but the one name stretches over both. Like bracken itself, it is often a mass noun, as in a hillside of brake.

  7. 7
    nouncountable or uncountable
    A fern of the genus Pteris, a group that includes many ornamental and table ferns.

    Florists often use brake in mixed foliage arrangements.

    A delicate brake unfurled new fronds along the shaded path.

    Note

    A clipped word: apparently bracken cut short, the way chick comes from chicken. It is a separate word from the stopping device and shares only its spelling. It works as both a countable and an uncountable noun. A brake is a single fern; brake, with no article, is a mass of them.

  8. 8
    nouncountable
    A thicket, or an area overgrown with briers, brambles, and other tangled growth.

    The fox vanished into a brake of thorns and bramble.

    We pushed through the brake to reach the riverbank.

    Similarthicket, brush, undergrowth, scrub

    Note

    The poets' thicket, from Old English *bracu, found in fearnbraca, "thickets of fern." That origin is why ferns and brakes keep company. Shakespeare's Venus and Adonis (1593) has "brakes obscure and rough," Wordsworth (1807) "a brake of fern," and Walter Scott (1808) a rider who "stayed not for brake." George Meredith (1859) spells it break, a reminder that the two words have long been confused.

  9. 9
    nouncountable
    A machine used to bend or fold sheet metal along straight lines.

    The shop bought a new brake to fold ductwork panels.

    She clamped the aluminum in the brake before forming the bend.

    Note

    The metalworker's brake belongs to a separate family: Late Middle English, from Middle Low German brake and Dutch braak. It shares that source with the tools that crush flax and break up clods. Whether this family is related to the stopping device is uncertain. In a workshop the word is about bending, not slowing, so "put it in the brake" means shaping sheet stock.

  10. 10
    nouncountable
    A large, heavy harrow dragged across plowed ground to break up clods of earth; a drag.

    They pulled the brake across the field to ready the soil for seeding.

    An ox team hauled the brake over the freshly plowed acres.

    Similarharrow, drag

    Note

    A farmer's word, and a good example of how literal this family is: the brake breaks the clods. Drag is its synonym in farm use. It also has a matching verb, to brake a field, meaning to pulverize the soil with this harrow.

Origins

Meanings 1–5, 11–18, 22–23

The origin is uncertain, but it possibly comes from Middle Dutch or Middle Low German 'brake' ("nose ring, curb, flax brake"), which according to Watkins is related to sense 4 and goes back to Proto-Germanic *brekaną ("to break").

Meanings 6–7

It is apparently a shortened form of 'bracken', much as 'chick' relates to 'chicken'.

Meaning 8

From Old English *bracu, attested in the plural compound 'fearnbraca' ("thickets of fern"), probably from Proto-Germanic *brekaną ("to break") and influenced by the "fern" sense. Compare Middle Low German 'brake' ("stump, branch").

Meanings 9–10, 19–21

Late Middle English, from Middle Low German 'brake', Dutch 'braak', and Old Dutch 'braeke'; possibly related to sense 1.
