strainer
UK: ˈstreɪnə | US: ˈstreɪnər
n. a device or utensil with perforations or mesh for separating solids from liquids or fine particles from coarse ones.
n. (figuratively) something that filters or refines, such as a process or system.
The word "strainer" originates from the verb "strain," which derives from the Latin stringere (to draw tight, bind). The concept evolved to mean filtering or separating by applying tension or pressure (e.g., straining liquid through a cloth). The suffix "-er" was added to form a noun denoting a tool that performs the action, hence "strainer" as a filtering device. The logic reflects the transition from the action (straining) to the object enabling it.
