Etymology

The noun is a Middle English merger of two words of the same origin:[1][5][6] inherited from Old English līne (“rope, cord; row, series”),[1][5] probably an early Germanic borrowing from Latin,[6][2][7] and ligne (about 1225, in “King Horn”), borrowed from Old French ligne (“guideline, cord; lineage”).[5][1] Both come from Latin līnea (“linen thread, string, plumb line”),[1][8] short for līnea restis (“linen cord”),[5][1] the feminine of līneus (“of linen, of flax”), from līnum (“flax, linen”).[1][8] The Old English word has cognates in Dutch lijn, Old High German līna (modern German Leine (“cord”)) and Old Norse lína.[2][6]

Earliest recorded meaning

A cord or rope, and a row or series: Old English līne is recorded before 900, in Solomon and Saturn,[5] and also meant a row of letters and a rule or direction.[1] The earliest Middle English sense is a builder's measuring cord.[1][9]

Semantic evolution

By 1425 almost all the ordinary modern senses had been recorded.[5] From the builder's cord came “a thread-like mark” and “track, course, direction” in the late 14th century,[1] and a line of descent (a line of kings) is also late 14th century.[1] The mathematical sense “length without breadth” is from the 1550s, as is “people or things in a row”,[1] now considered American English, where British English says queue, though the sense appears first in British writers.[1] A crease in the face or palm is a line from the 1530s, the equator from the 1580s, and a boundary from the 1590s.[1] The sense “occupation, branch of business” (1630s) comes, according to the OED, from a misunderstood verse of the King James Bible (2 Corinthians 10:16, “another man's line”).[1] The verb “to mark with lines” is from the mid-15th century, and “to arrange in a line” from the 1640s.[1][5] A liner was a ship of a shipping line from 1829 and a cosmetic for the eyes from 1926.[5]

Etymology

The verb meaning “to put a lining in” is formed from the obsolete noun line “flax, linen”,[1][2][3] inherited from Old English līn (“flax, linen”), from Latin līnum (“flax, linen”),[1][2] because linen was much used for linings.[1][3]

Earliest recorded meaning

To cover the inside of something, recorded about 1387 in Chaucer;[5] Etymonline dates it to the late 14th century.[1]

Semantic evolution

“To fill plentifully”, as in line one's pockets or line one's stomach, is from the 1510s.[1] The noun lining, the material covering an inside surface, is formed from the verb.[2][10]

  • 1510s – to fill plentifully.[1]
