alignment

Etymology

It was formed from English align + -ment in English, on the model of alignement,^[2] and Etymonline, Merriam-Webster and the Oxford Dictionary of English simply derive it from the French noun.^[3][4][5] In French alignement meant the official marking out of a public road in 1387, an arrangement in a straight line in 1397, and a line of soldiers from 1774.^[2] The French noun comes from aligner (“to arrange in a line”),^[3][6] itself alignier (“to set in line”), made of à (“to”) and ligne (“line”),^[3][7][8] from līnea (“line”).^[7] Dictionary.com and Merriam-Webster also record the spelling alinement.^[9][4]

Earliest recorded meaning

The result of arranging things in a line or in their proper relative positions: 1742, in a translation of the Philosophical History of the French Academy of Sciences.^[2][10] Merriam-Webster also dates its first sense to 1742,^[4] while Etymonline gives 1790 and Dictionary.com 1780–90.^[3][9]

Semantic evolution

The word began in the practical language of surveyors, soldiers and engineers: a line of soldiers from 1781,^[2][8] the route of a road, railway or canal from 1810,^[2] and the act of bringing things into line from 1829.^[2][10] In archaeology it has named a row of three or more standing stones since 1831.^[2][11] The political sense, a grouping of parties or powers with shared goals, is recorded from 1866,^[2][10] though Etymonline dates it to 1933.^[3] The phrases in alignment and out of alignment (1807 and 1841) gave the figurative sense of agreement or its lack.^[2] Biochemists have used it since 1960 for matching protein or nucleic-acid sequences.^[2]
