Full of foam or froth; having many bubbles on the surface; light and bubbly in appearance or texture.
From 'foam' (Old English 'fam', meaning froth) + '-y' (adjective suffix), creating a descriptor for the quality of being foam-filled or frothy.
The adjective 'foamy' has stayed popular for centuries because it describes a precise visual and textural quality—coffee with a foamy head, ocean waves with foamy crests—that's impossible to replace with a single other word.
