Late Middle English (denoting the time during which something, especially a disease, runs its course): from Old French periode, via Latin from Greek periodos 'orbit, recurrence, course', from peri- 'around' + hodos 'way, course'. The sense 'portion of time' dates from the early 17th century.
When first used, period referred to the time during which something such as a disease, ran its course. It goes back to Greek periodos ‘orbit, recurrence, course’, from peri- ‘around’ and hodos ‘way’. The sense ‘portion of time’ dates from the early 17th century, as does use of the word to mean ‘full stop’, now part of US English. Peri is also found in peripatetic (Late Middle English) now meaning ‘wandering, travelling’ but from Greek peripatetikos ‘walking up and down’ and originally applied to followers of the ideas of Aristotle ( 384–322 bc), who is said to have walked about while teaching; and periphery (late 16th century) originally the boundary of something. Hodos, the second part of period is also found in episode (late 17th century), literally ‘coming in beside’ from epi ‘addition’ and eisodos ‘entry’ (formed from eis ‘into’ and hodos); and exodus, ‘departure’ formed in the same way using ex- ‘out of’.
