Etymology

It is borrowed from Latin mergō (“to dip, plunge, immerse”),[2][3][4][5][6] and in its legal senses it came through the Law French infinitive merger (“to drown, sink”).[2][7][8][9] The Latin verb is probably a rhotacized form of an older *mezgō,[3][10] from Proto-Indo-European *mezg- (“to dip, sink, wash”),[3][11] the source also of Sanskrit मज्जति (májjati, “dives, sinks”) and Lithuanian mazgoti (“to wash”).[3][10][2][6] The same Latin verb gave emerge, immerse and submerge.[12][10]

Earliest recorded meaning

To plunge or immerse oneself in an activity, way of life or surroundings: 1636, in William Prynne,[2][4][6] a sense the OED records only until 1751.[2][13] From 1660 the verb also meant to plunge something into a liquid, a use that died out in the 19th century.[2]

Semantic evolution

The modern meanings grew out of law.[2][14] From 1726 the verb was used of a lesser estate, title or right that is absorbed into a greater one and so ceases to exist,[2][4][3] while from 1728 it was used transitively, of causing it to be absorbed;[2][4] Weekley compares other legal terms taken from Anglo-French infinitives, such as misnomer and rejoinder.[9] Generalized, the verb came to mean "to be swallowed up, lose one's identity in something else".[3][2] The commercial sense, to combine separate companies into one, is recorded from 1836 in Washington Irving,[2] and Barnhart dates the business sense of the noun merger to 1889.[4] Ayto notes that the everyday meaning "to combine into one" was not fully established until the 20th century.[12] Melville used merge into for a gradual change in 1849.[2] Since 1924, first in North America, the verb was applied to lanes of traffic joining.[2] The noun merge, a merger, appeared in 1806, and the traffic noun in 1956.[2][3]
