'periodically-banned' originates from the combination of 'periodically' and 'banned'. 'Periodically' comes from 'period', which originates from Greek 'periodos', meaning 'a way around' or 'circuit'. 'Banned' comes from Old English 'bannan', meaning 'to summon' or 'to proclaim'.

'Periodically' evolved from the Greek 'periodos' through Latin 'periodus' and Old French 'periode', while 'banned' evolved from Old English 'bannan' to Middle English 'bannen'.

Initially, 'periodically' meant 'in a regular cycle', and 'banned' meant 'proclaimed'. Over time, 'banned' evolved to mean 'prohibited', and 'periodically-banned' now means 'banned at intervals'.
