    A connected series of public conveyances or the route they run on, such as a railroad track or an established shipping service.

    Engineers inspected the line before the first train of the day.

    UsageOften named: the red line, the Elizabeth line. Also a shipping line, a bus line.

    Similarroute, track, service, company

    Note

    Transport lines cover the road as well as the rail: a line of stages runs coaches along a set route, and an express line forwards goods as well as passengers. The word names the established service as much as the track, which is why a railway route and a shipping company are both called lines.

  4. 4
    nouncountable
    The outer limit of a figure or territory; a boundary, contour, or outline.

    Surveyors traced the property line along the old stone wall.

    Our house sits just past the city line, so we pay county taxes.

    UsageCommon in property line, city line, state line and the line between two yards.

    Similarboundary, border, outline, contour, edge

    Note

    The outer limit of a thing, with boundary, contour and outline as close partners. It can mean the extent of a territory as well as the edge of a shape.

    product rangenouncountable
    The range of goods or services a company offers, or by extension the company itself.

    Their budget line of laptops outsold the premium models.

    UsageA line of products: a new line of sneakers, a product line. Companies launch or expand a line.

    Similarrange, collection, series

    Note

    Commerce stretches the word from what is sold to who sells it. A product line is a range of goods. By extension, a company, often a transport company, can itself be a line, so a ferry line can add a new boat to its fleet, and airline is built on the word. In the plural it means each producer's goods: the Illinois State Dairymen's Association's Annual Report of 1890 boasts of the best of everything in their lines.

    Stay on the line and an agent will be with you shortly.

    UsageCommon in stay on the line, hold the line and the line went dead.

    Similarconnection, cable, wire

    Note

    The wire has become the call. Telegraph stations once needed a physical wire between them. Now line means the connection itself, and English judges it by ear: a line is dead, or faint. Dedicated and shared lines describe who has the connection to themselves. The same word covers telegraph wire, telephone cable and network link alike.

    The tailor lined the coat with silk.

    Workers line the tunnel walls with concrete for safety.

    UsageLine something with a material: lined the coat with silk.

    Similarface, coat, cover

    Note

    Despite the spelling, this is a different word from the one for marks and rows. It comes from Old English līn, meaning flax or linen, so to line a cloak was first to put linen inside it. Silk, fur, paper and tin followed. Bookshelves lining a hallway blur it with forming a row along, but here the sense is covering, not arranging.

    A sentence of dialogue, especially one spoken by an actor in a play, movie, or similar work.

    He delivered the final line with perfect comic timing.

    The director asked her to repeat the lines more slowly.

    UsageActors learn, forget or deliver their lines. A pickup line is a set phrase used to start flirting.

    Note

    The actor's sense, and the one behind learning your lines. A chapter in Actor Training, a book edited by Alison Hodge, recalls Littlewood's rehearsals, where each actor in turn spoke a single line until the right intonation and emphasis emerged. Outside the theater, the word attaches to any well-worn sentence, such as a pickup line or a catchphrase. That use shades toward the line as smooth deception.

The construction in the ___ line names a business casually, as in Norman Lindsay's Dust or Polish? (1950): There ain't anybody but me in the furniture restoring line.

    A trench or defensive barrier, or the boundary marking how far a military force's territory extends.

    UsageCommon in hold the line, break through the line and the front line.

    Similarfront, trench, barrier

    Note

    War gives the word its hardest edge. A line can be a trench or rampart that is held, or an invisible limit showing how far an army's ground reaches. The same word also names the regular infantry, so context decides whether a line means earthworks, territory or soldiers. Here it is the place, not the people standing in it.

The phrase is the natural home of this sense; on its own, line rarely means simply "direction."

Origins

Meanings 1–8, 10–34

From Middle English line, from Old English līne ("line, cable, rope, row, direction"), going back through Proto-Germanic words for rope and thread to a word for flax, shared with Latin līnum, whose deeper origin is uncertain. It was also influenced in Middle English by Middle French ligne, from Latin linea. Its oldest sense was "rope, cord, thread," from which the senses "path" and "continuous mark" developed.
