The word "thick" traces back to Old English þicce, meaning "dense, viscous, or sturdy," derived from Proto-Germanic þekuz. It shares roots with German dick and Dutch dik. The core idea of "density" or "close-packed" has persisted through its evolution, later extending metaphorically to describe stupidity ("thick-headed") or intensity ("thick of things").
