Pronunciation

  • /dɪsˈfʌŋk.ʃən/[1]

Etymology

It is formed from English dys- + function,[2][3][4][5] and Merriam-Webster also allows dis- as the prefix, with the less common spelling “disfunction”.[6][3] The prefix comes from Ancient Greek δυσ- (dus-, “bad, ill, hard”),[4][7] from Proto-Indo-European *dus- (“bad, ill”),[4] and is related to Old English tō-, Old High German zur- and Old Norse tor-.[7][4] The base comes from French fonction and directly from Latin fūnctiō (“a performance, execution”), from fungor (“to perform, discharge”).[4][7]

Earliest recorded meaning

Abnormal or impaired function, at first in anatomy and medicine: 1914, according to Etymonline;[4] the OED's first record is from 1916, in the third edition of Gould's Practitioner's Medical Dictionary,[2] and Merriam-Webster also dates it to about 1916.[6] Dictionary.com gives 1915–20.[5]

Semantic evolution

The word was used in sociology by 1949,[4] for a trait or condition that fails to serve a useful purpose in society.[6] It later came to be used of relationships and especially families that fail to behave in ways accepted as normal or healthy.[8][9] The adjective dysfunctional is dated 1915 by Etymonline and 1936 by the OED.[4][2]
