Take rain check意思

"Take a rain check" is an English idiom that means to postpone something, often an invitation, to a later time. The phrase is believed to have originated in the United States in the late 19th or early 20th century. It was originally used in the context of baseball, where if a game was rained out, fans would be given a "rain check" – a ticket that could be redeemed for admission to a future game.

Nowadays, the phrase is used more broadly to mean that one is declining an invitation or offer today, but would like to accept it at a later date. For example, if you were invited to a party but couldn't go, you might say, "I'd like to take a rain check on that invitation." It implies that you are not rejecting the invitation outright, but rather agreeing to reschedule for a more convenient time.
