Pronunciation

  • /ˈnɛksəs/[1]
  • UK: /ˈnɛksuːs/[1]
  • US: /ˈnɛksus/[1]

Etymology

It is borrowed from Latin nexus (“the action of binding; a bond, tie; a connected group”),[2][3][4][5] a noun formed from nectō (“to bind, connect”) with the suffix of verbal nouns -tus.[2][6] In Roman law the word also named a kind of legal obligation.[2] The verb comes from Proto-Indo-European *ned- (“to bind, tie”).[4][5] It is related to connect and annex.[3][7][8]

Earliest recorded meaning

A bond or link; a means of connection between things or parts: 1663, in Robert Boyle.[2][3][8]

Semantic evolution

The sense "a connected group or series" followed in 1858,[2] in the 19th century according to Hoad.[9] In the 20th century the word was taken up by specialists: Otto Jespersen used it in 1924 for a group of words expressing a predicative relation,[2][8] and cell biologists from 1962 for an area of close contact between two cell membranes.[2] The sense "a central point, a focus or meeting place" is recorded from 1971.[2] The plural is either nexus, as in Latin, or nexuses.[10][8][11]
