Etymology Origin:
The word "latch" traces back to Old English læccan, meaning "to seize or grasp." Over time, it evolved into Middle English lacchen, retaining its core sense of holding or fastening. The modern spelling "latch" emerged by the 14th century, specifically referring to a mechanical fastening device. The morpheme lat preserves the original idea of seizing, while the suffix ch marks its verbal function. The word’s progression reflects a shift from abstract action ("to grasp") to a concrete tool ("a fastening mechanism").
