A cold snap is a sudden drop in temperature, often accompanied by strong winds. The term can be broken down into four parts: CHILL (5 letters), brr (3 letters), icicle (6 letters), and PHOTO (5 letters). CHILL is a verb meaning to make or become cold, while brr is an expression of coldness. Icicle is a frozen drop of water that hangs from a surface, and PHOTO is short for photograph. Together, these words describe the sudden coldness of a cold snap.
