beam
Pluralbeams
Pluralbeams
- 1A ray or narrow stream of light, other radiation, or particles sent out from a source; also, figuratively, a gleam of something such as hope or humor.
A single beam of sunlight broke through the clouds over the valley.
Lighthouse beams swept the coastline every few seconds through the fog.
UsageOften a beam of light or energy; a car's headlights can be on high beam or low beam.
Similarray, shaft, stream, gleam
Note
Physics uses the word for a bundle of nearly parallel rays, and that is what sets it apart from a single ray: a beam has breadth as well as direction. Shakespeare already has a candle that "throws his beames" in The Merchant of Venice.

- 2A long, strong piece of timber, steel or concrete, especially one of the main horizontal supports of a building or structure.
The contractor replaced a cracked beam before finishing the renovation.
Exposed ceiling beams give the converted loft an industrial look.
Note
In a building the word narrows to the main horizontal members, the ones that span a space. The material usually comes first: steel beams, concrete beams, oak beams, or the wooden beams of the kitchen hidden inside a hill in Beatrix Potter's The Tale of Mrs. Tiggy-Winkle (1905). Horizontal is the usual case, though sloping beams are common in roofs. An upright member is normally called a post or a column.

- 4Of the sun, a lamp, or another light source, to send out rays and shine.
Headlights beam through the fog on the mountain road.
The full moon beamed over the quiet harbor all night.
Similarshine, glow, stream, radiate
Note
The verb works with or without an object. Without one, the light-giver simply shines: the moon beamed over the harbor. With one, the verb sends something outward, as in "to beam forth light," or a figure who "beams golden light from his solar plexus." The transitive use sits close to the later verbs of transmission.

UsageFor the event, often on beam: she competes on beam. For the apparatus, usually the beam: she fell off the beam.
Note
A clipping of balance beam that covers both the apparatus and the event. The full compound also names the bar of a weighing scale, which plain beam names too, but as a clipping the word belongs to gymnastics.

- 8To send signals, broadcasts, or data without wires, by radio, satellite, or a direct link such as infrared between two devices.
Early handheld organizers could beam contact cards to each other over an infrared link.
The payment terminal beams a receipt straight to the customer's phone.
UsageOften passive with a destination: beamed live around the world, beamed to a phone.
Note
The real-world cousin of the teleporter verb, used for signals and data instead of people. Broadcasting gave it the long-range sense, as when a World Cup is beamed live around the world by satellite. Handheld devices brought the short-range kind: Michael Miller's 10 Minute Guide to Pocket PC 2002 explains how "to beam a file to another Pocket PC." Either way, the core idea is a signal aimed through the air at its receiver.

Less common meanings
- 10A broad smile spreading across the face.
His face broke into a beam as the bride walked in.
The coach's usual frown gave way to a broad beam as the final whistle blew.
Note
It behaves like smile or grin, as something worn on the face and hard to take off. Phil McNulty's 2023 BBC piece on Declan Rice has a player who "could barely remove the beam from his face." It is more common as the smiling verb than as a noun. As a noun it implies a smile wide and open enough to seem to shine.
- 11The direction across a vessel, at right angles to its fore-and-aft line.
Heavy swells rolling in on the beam made the crossing uncomfortable.
The captain spotted the buoy just off the starboard beam.
Note
A direction rather than an object, and the anchor point for a set of positional terms. A landmark straight off the side is abeam. Once the ship has passed it, the landmark falls abaft the beam, and finally it falls astern. Sailors also speak of the port or starboard beam, and of seas or wind "on the beam," meaning they strike the vessel squarely from the side.

- 12The horizontal crossbar of a mechanical balance, from whose ends the weighing pans are suspended.
The pharmacist added small weights until the beam swung level.
Dust on the beam can throw off a sensitive balance's readings.
Note
The weighing sense, and one that lends itself to images of uncertainty. A beam that has not settled is a mind that has not decided. In Alexander Pope's The Rape of the Lock, "the doubtful beam long nods from side to side." The full name is balance beam, the same compound that gymnastics uses for its narrow rail.

- 13One of the transverse members of a ship's frame on which the decks are laid, also helping hold the sides of the hull in shape.
In dry dock, the shipwrights replaced a cracked beam under the schooner's main deck.
The deck beams of the schooner were notched into the frames along each side.
Note
Shipbuilding's crosswise timber runs from side to side under the deck planking. In a wooden hull, knees fasten it to the frames at each end; steel ships use bracket plates for the same job. Its ends give the phrase beam ends: a vessel thrown on her beam ends has been knocked onto her side, often by a sudden squall, as Richard Hall Gower describes in A Treatise on the Theory and Practice of Seamanship.

- 14A horizontal bar connecting the stems of two or more notes to group them and show their rhythmic value.
In the second measure, one beam links the four eighth notes so the player can see the beat at a glance.
Beams in older vocal scores often follow the syllables of the text rather than the beat.
Note
An engraver's alternative to separate flags. When notes shorter than a quarter note are joined, the bar takes over the flag's job. The number of bars carries the rhythm: one for eighth notes, two for sixteenths. Beams may slant to follow the melody. Their other job is to show where the beats fall, and choosing that grouping is what the verb describes.

Note
Notes can be beamed in different ways, and the choice tells a player where the beats fall. Composers and engravers usually group eighth and sixteenth notes so that each group matches a beat of the meter. Notation software follows the same principle when it beams automatically. A badly beamed bar is harder to read even though no note in it has changed.

- 16The principal stem of a deer's antler, from which the individual tines branch.
The old stag carried antlers with a beam as thick as a man's wrist.
Each beam swept back and then curved forward over the deer's ears.
Note
Hunters and naturalists use this word for the main shaft of each antler, the one the tines branch from. It belongs to the vocabulary of trophy scoring, where beam length and beam circumference are standard measurements. A description of a rack will often praise the beams for their mass and the tines for their number.

Origin
From Middle English beem, from Old English bēam ('tree, wood, post, rafter'), from Proto-West Germanic *baum and Proto-Germanic *baumaz ('tree, beam'), traditionally traced to Proto-Indo-European *bʰew- ('to grow, swell'). It is cognate with Dutch boom, German Baum, and Yiddish בוים (boym), all meaning 'tree', and is a doublet of boom. The verb is from Old English bēamian ('to shine, to cast forth rays of light'), formed from the noun.
