crease
UK: kriːs | US: kriːs
n. a line or ridge produced on paper, cloth, etc., by folding or pressing
vt. to make a crease in something by folding, pressing, or crushing
vi. to become creased
The word "crease" originated in the late 16th century, likely derived from the Old French word creisse (a notch or fold), which itself traces back to the Latin crispa (wrinkled or folded). The morpheme creas preserves the core idea of folding, while the silent -e is a common suffix in English with no semantic role. The word’s evolution reflects its practical association with folded or wrinkled textures, particularly in fabrics or paper.
