n. a projecting flat rim, collar, or rib on an object, serving for strengthening, attachment, or positioning.
vt. to provide with a flange.
The word "flange" first appeared in the late 17th century, but its exact origin remains uncertain. Some linguists suggest it may be of imitative origin, mimicking the sound or appearance of a protruding edge. Others propose a connection to Old French flanc ("side"), though the spelling divergence makes this theory speculative. The silent "e" is a common feature in English to preserve the soft "g" sound. Despite its unclear roots, "flange" has consistently referred to a rim or ridge in mechanical and engineering contexts.
