What does winnowing mean?
Winnowing is the process of separating grain from chaff, traditionally by tossing the grain into the air so that a breeze carries away the lighter, unwanted chaff. Historically, the word also referred to a winnowing machine and could mean the act of threshing or dressing grain. In modern usage, winnowing is especially common as a metaphor for carefully sorting through information, applications, or options and keeping only the most valuable or suitable ones. Phrases such as “winnowing out” suggest deliberate discrimination rather than an arbitrary loss. The word can sound literary or formal, but its vivid agricultural origin makes it useful for describing any process in which a valuable core is separated from what is considered less useful.
