convergence
Pronunciation
Etymology
It is formed from English convergent + -ence,[2][3][4] though Etymonline and Klein derive it from the verb converge with the same suffix.[5][6] convergent comes from the present participle of Late Latin convergō (“to incline together”),[2] a verb first found in Isidore,[2] formed from com- (“with, together”) and vergō (“to bend, turn, incline”).[2][5][7] Etymonline and the American Heritage Dictionary trace the Latin verb to Proto-Indo-European *wer- (“to turn, bend”).[5][7]
Earliest recorded meaning
The action or fact of converging, movement toward a single point: 1713, in W. Derham's Physico-Theology.[2][5][8]
Semantic evolution
The word began as a term of geometry and physics for lines or movements meeting in a point,[2] and was soon used of the degree or point of convergence itself (1855).[2] The figurative sense, a coming together of operations or effects, is recorded from 1843, in Gladstone.[2] In mathematics it was used of convergent series from 1858,[2] and in biology, from Darwin's third edition of the Origin of Species (1861), for the tendency of unrelated plants and animals to develop similar features under similar conditions;[2] Etymonline dates this biological use to 1866.[5] Meteorology (1906) and oceanography (1933) gave it senses for converging winds and currents,[2] and in 1958 economists named a theory that all social and economic systems tend toward similar patterns, now little held.[2] Since 1978 it has also meant the merging of once separate technologies, such as telephones, computers and television, into combined devices.[2][9]
