The term 'bridge utterance' is used to describe a type of communication between two people in a bridge game. The most common bridge utterances are 'PASS', 'BID', and 'iPass'. 'PASS' is a four-letter word that indicates a player's decision not to BID on a hand. 'BID' is a three-letter word that indicates a player's decision to BID on a hand. 'iPass' is a five-letter word that indicates a player's decision to PASS on a hand, but with the intention of bidding on the next hand.
