[Middle English periode, from Old French, from Medieval Latin periodus, from Latin perihodos, rhetorical period, from Greek periodos, circuit : peri-, peri- + hodos, way.]
Synonyms: These nouns refer to a portion or length of time. Period is the most general: a short waiting period; a difficult period of my life; the Romantic period in music. Epoch refers to a period regarded as being remarkable or memorable: "We enter on an epoch of constitutional retrogression" (John R. Green).
An era is a period of time notable because of new or different aspects or events: "How many a man has dated a new era in his life from the reading of a book" (Henry David Thoreau).
An age is usually a period marked by a distinctive characteristic: the age of Newton; the Iron Age.
A term is a period of time to which limits have been set: Senators are elected for a term of six years.
Word History: Many may have wondered why the word period has the sense "punctuation mark ( . )" as well as several senses having to do with time. The answer to this question lies in one of the senses of the Greek word periodos from which our word is descended. Periodos, made up of peri-, "around," and hodos, "way," in addition to meaning such things as "going around, way around, going around in a circle, circuit," and with regard to time, "cycle or period of time," referred in rhetoric to "a group of words organically related in grammar and sense." The Greek word was adopted into Latin as perihodos, which in the Medieval Latin period acquired a new sense related to its use in rhetoric, "a punctuation mark used at the end of a rhetorical period." This sense is not recorded in English until 1609, but the word had already entered English as a borrowing from Old French in the sense "a cycle of recurrence of a disease," first being recorded in a work written around 1425.
1413, "course or extent of time," from M.L. periodus "recurring portion, cycle," from L. periodus "a complete sentence," also "cycle of the Greek games," from Gk. periodos "rounded sentence, cycle, circuit, period of time," lit. "going around," from peri- "around" + hodos "a going, way, journey" (see cede). Sense of "repeated cycle of events" led to that of "interval of time." Meaning "dot marking end of a sentence" first recorded 1609, from similar use in M.L. Sense of "menstruation" dates from 1822. Educational sense of "portion of time set apart for a lesson" is from 1876. Sporting sense attested from 1898.

4.
