24 meanings of flare

Practice

  1. 1
    nouncountable
    A pyrotechnic device that gives off a brilliant light without exploding, used to signal in an emergency, to light up an area, or as a decoy.

    The stranded hikers lit a red flare as soon as they heard the helicopter.

    Soldiers sent flares up into the night sky to light the field ahead of them.

    Note

    A pyrotechnic you light, fire or send up, built to burn rather than explode. Its three jobs explain where it turns up: red and green signal cartridges for a rescue, flares on the road to steer traffic past an accident, and flares released as decoys to draw off heat-seeking missiles. One shot up over a battlefield hangs from a small parachute, lighting the ground below.

  2. 2
    nouncountable
    A sudden burst of bright light.

    A sudden flare from the fireplace lit up their faces for a moment.

    Each flare of the distant lightning showed the outline of the hills.

    Similarflash, burst, blaze, glare

    Note

    The word's beginnings are uncertain. It is first recorded in the mid 16th century and is probably related to Latin flagrō, "I burn"; Norwegian flara, "to blaze," looks similar but comes later. Suddenness is the core of this use: a flare from the fireplace or of distant lightning lasts a moment, which is what separates it from a steady glow.

  3. 3
    verbfigurativelyintransitive
    To break out suddenly, or to grow suddenly more intense.

    Tensions between the two families flare up every time the old land dispute comes back.

    Violence flared across the city after the verdict was announced.

    Similarerupt, escalate, intensify

    Oppositesubside

    Note

    Usually met as the phrasal flare up, said of tensions, troubles and outbreaks that come back. The image is a fire that catches again: James Davenport Whelpley wrote in 1851 that the genius of Keats flares up, dies out, and flares again, as if there were a dearth of fuel to feed it. The word suits anything that recurs in bursts rather than steadily.

  4. 4
    verbtransitive or intransitive
    To widen or open outward in shape, or to make something do so.

    Potters flare the rim of a bowl by pressing outward as the wheel turns.

    The tower flares outward near the top, giving it the shape of a trumpet.

    Similarwiden, splay

    Oppositetaper, narrow

    Note

    One verb, two constructions, both everyday: a cat flares its nostrils, or its nostrils flare. The intransitive use describes the shape something has (the sides of a bowl flare, a building flares out over its entrance plaza), while the transitive one describes making it so. Nostrils, rims and the walls of buildings are its usual subjects.

  5. 5
    verbintransitive
    To shine out with a sudden, unsteady light, or to give off a dazzling, painfully bright light.

    The oil lamp flared and smoked whenever the wind found the cracks in the cabin wall.

    Headlights flare in the rearview mirror, and for a moment she can't see the road.

    Similarflash, flicker, glare, blaze

    Note

    Here the stress falls on unsteadiness: the light jumps rather than glows, as a candle does in a sudden draft. A candle that flares usually smokes as well, and The Working Man's Friend of 1850 explained why: the flame throws off unburnt charcoal, the same finely divided carbon that gives ordinary flames their brightness.

  6. 6
    verbfigurativelyintransitive
    To burst out suddenly in anger.

    She tends to flare up whenever anyone questions her judgment.

    The coach flared up when the referee waved off the goal.

    Similarexplode, erupt, bristle

    Note

    People are the subject here, and the usual shape is the phrasal flare up: he flared up when I told him. It appears in plain official prose as early as the Reports of Committees of the House (1868), so it is no modern slang. Where the "break out" meaning tracks troubles, this one tracks a temper that rises fast and shows.

  7. 7
    nounfigurativelycountable
    A sudden eruption or outbreak of something.

    Moisturizing every day can help prevent a flare of eczema.

    After months of calm, a flare of violence along the border forced villagers to flee.

    Similaroutbreak, eruption, outburst

  8. 8
    nouncountable
    An inflammation, for example of the tendons in tendonitis or of the joints in osteoarthritis.

    An osteoarthritis flare in her hip forced her to cancel the hiking trip.

    Runners who ignore a tendon flare often end up with a longer injury.

    Similarflare-up

    Note

    The medical use, and the noun partner of the verb "to inflame": a flare is a spell of inflammation in tendons or joints, and flare-up means the same. The condition usually comes first in the phrase, as in an arthritis flare or a tendon flare, so the word rarely needs anything after it.

  9. 9
    verbintransitive
    To burn or shine with a bright, strong blaze.

    Beacon fires flare on the hilltops every year during the festival.

    Torches flared along the castle walls as the guests arrived.

    Similarblaze, burn, flame

    Note

    Fire is the native subject here (furnaces, beacons, torches) and older verse uses it freely, down to the forms flareth and flarest. The phrasal flare up begins in this literal blaze: Charles Mackay, writing in 1850, traces the cry "Flare up!" to the Reform riots, when Bristol was nearly half burned and the flames were said to have flared up.

  10. 10
    nouncountable
    A widening at some point along an object that is otherwise of roughly even width.

    The plumber shaped a flare on the end of the copper tubing so it would seal tightly against the fitting.

    The skirt is fitted at the hip, with a gentle flare below the knee.

    Similarwidening

    Note

    The shape word behind several trades' vocabulary: plumbers seal tubing with a flare fitting and a flare nut, fashion writers note where the flare falls on a skirt or coat, as Vogue did in 1917, and running shoes carry a flare on the inside to resist pronation. It names the widening itself, so you can say where it sits and how much of it there is.

Origin

Of unknown origin, first recorded in the mid 16th century and probably related to Latin flagrō ("I burn"). Norwegian flara ("to blaze; to flaunt in gaudy attire") is similar in meaning but later than the English word, and a link to Middle High German vlederen ("to flutter"), modern German flattern, is possible; the noun comes from the verb.
