flush

You might flush with embarrassment when you trip in front of a crowd, and your face suddenly turns warm and red. The word is also used when water rushes through something to carry waste or dirt away, like when a toilet flushes or when you flush out a pipe. In poker, a flush is a hand with five cards of the same suit. It can also mean that two surfaces are perfectly even, like a cabinet door sitting flush with the wall. And if someone is flush with cash, they have plenty of money for the moment. The word often carries the idea of a rush, a smooth even line, or having plenty of something.

The word "flush" changes its meaning easily from one situation to another, from carpentry to card games. Its main ideas usually involve a sudden rush, plenty of something, or being perfectly even with a surface.

First, it can describe a reddish glow on the skin, usually on the face. You might flush with anger, fever, exercise, or embarrassment. In this sense, blood seems to rush to the surface. For example, "A sudden flush crept over his cheeks when he realized his mistake."

Second, "flush" refers to a strong flow of liquid used to clean or carry something away. We most often think of a toilet flushing, but the term also applies to things like flushing a pipe, a radiator, or a wound with water. This idea can also be used more broadly: police may flush a fugitive out of hiding, or doctors may talk about flushing harmful material from the body.

Third, in the world of games and money, a "flush" is a poker hand made of five cards of the same suit. By extension, the word can also mean well supplied or full of something. If you have just been paid, you might be "flush with cash," and a writer might be "flush with new ideas."

Finally, in technical and DIY contexts, "flush" means even or aligned. When two surfaces meet without any overlap or raised edge, they are flush. A carpenter might want a drawer handle to sit flush with the wood for a smooth, clean finish.

The word's history likely goes back to older words linked to rushing or flowing. That helps connect its modern uses, whether it is blood rising to the skin, water moving through a pipe, money being plentiful, or one surface meeting another in a perfectly smooth line.
