The word "sieve" refers to a tool used for separating wanted elements from unwanted material or for controlling the texture of a substance. It typically consists of a mesh or perforated surface, through which smaller particles can pass while larger particles are retained. Sifting flour or straining liquids are common examples of how a sieve is used in cooking and food preparation.
The word "sieve" comes from the Old English word "sife," which is derived from the Proto-Germanic word "*sifō," meaning "to sift." It has cognates in various Germanic languages, indicating a longstanding use of this tool throughout history.
