defunct: [16] The -funct in defunct is the same ultimately as that in function and perfunctory. It comes from the past participle of Latin fungī ‘perform, discharge’. In combination with the intensive prefix dē- this produced dēfunctus ‘discharged, finished’, hence ‘dead’, which was borrowed directly into English. => function, perfunctory
defunct (adj.)
1590s, from Old French defunct (14c., Modern French defunt) or directly from Latin defunctus "dead," literally "off-duty," from past participle of defungi "to discharge, finish," from de- "off, completely" (see de-) + fungi "perform or discharge duty," from PIE root *bheug- (2) "to enjoy" (see brook (v.)).
