FLUSH, a.

1. Fresh; full of vigor; glowing; bright. Flush as May. Shak.
2. Affluent; abounding; well furnished. Lord Strut was not very flush in ready. Arbuthnot.
3. Free to spend; liberal; prodigal. He is very flush with his money. This is a popular use of the word in America. A flush deck, in seamen's language, is a deck without a half-deck forecastle. [Qu. Russ. ploskei, flat. The sense of spreading naturally results from that of flowing.]
