away (adv., adj., n., intensifier), way (adv., adj., intensifiers)
Way (it is sometimes spelled way) is a clipped or aphetic form of away; it has some of the adverbial and intensifier meanings that away has, but its use in these senses is restricted mainly to dialectal, Conversational, and Informal uses: Go away [way]; I thought he was way off in his estimates. In other adverbial uses, away is never clipped: I went away for the day. And away we go! As a noun, away appears when natives of places where we vacation observe that were from away. As an adjective, away is often idiomatic, with special senses in (for example) sports: Youre away (in golf), means your ball is farther from the hole, and therefore you must play first; Theyre playing three away games in a row (in team sports of all kinds, where home games are on the teams own field or court, and away games are played on the other teams); His home run came with two away in the ninth (in baseball, this means that two were out). Limit such uses to relevant contexts. See WAY (2).
