What's the difference between i.e. and e.g.?
c.1600, "a way of approach" (originally a military word), from Middle French avenue "way of access," from Old French avenue "act of approaching, arrival," noun use of fem. of avenu, past participle of avenir "to come to, arrive," from Latin advenire "to come to," from ad- "to" (see ad-) + venire "to come" (see venue). Meaning shifted to "a way of approach to a country-house," usually bordered by trees, hence, "a broad, tree-lined roadway" (1650s), then to "wide, main street" (by 1846, especially in U.S.).
