I donned the hip-hop attire (not very well), and dreamed of an alternate life as a girl tagger.
In real life, there is a nursing shortage, but the alternate universe of television addresses reality more symbolically.
I entered this alternate universe when I was researching my book The Diana Chronicles.
1510s, from Latin alternatus "one after the other," past participle of alternare "to do first one thing then the other; exchange parts," from alternus "one after the other, alternate, in turns, reciprocal," from alter "the other" (see alter). Alternate means "by turns;" alternative means "offering a choice." Both imply two kinds or things.
1718, "that which alternates (with anything else)," from alternate (adj.). Meaning "a substitute" is first attested 1848.
