The phrase 'Call It Off' means to decide not to do something that was planned.
Example of Use: "Tonight's game was called off because of the rain."
The origin of the idiom 'call it off' has its roots in the late 14th century, from the Anglo-French word 'repeler', meaning to call in, call back, call after, or revoke. In the 1580s, the term 'recall' became popular for describing the act we know today as calling something off. The word 'recall' remains common, but is rarely used in casual settings and has a slightly different meaning now than it did when first coined.
