Pronunciation
- IPA: /ˈfælæŋks/ (UK); /ˈfeɪˌlæŋks/ (US)[1]
Etymology
It is borrowed from Latin phalanx,[2][3][4][5][6] from Ancient Greek φάλαγξ (phálanx, “line of battle; finger or toe bone”),[2][3][4][5][6] originally “log, trunk”,[3][4][5] a word of unknown origin.[4] Etymonline suggests it may come from a Proto-Indo-European root meaning “plank, beam”, the source of balk.[4][5] An earlier English form was phalange (before 1460).[3]
Earliest recorded meaning
An ancient Greek battle formation in close ranks (1553).[3][4][5][7]
Semantic evolution
In anatomy the word first named the whole row of finger joints, which fit together like infantry in close order,[4] and then a single bone of a finger or toe (1693).[7][5] Figuratively it has meant a group of people banded together in a common cause since 1600,[7][4] and a compact mass of people, animals or things since 1733.[7][5] In Fourier's social system it was a community living in a phalanstery (1843).[7][2][6]
