matter pretending to be solid while being mostly desperate, trapped air
means A mass of small bubbles formed on or in a liquid, trapping air to create a light, frothy layer.
from From Old English 'fām,' meaning froth or foam, with deep Germanic roots — it's a cousin of German 'Feim' and possibly related, far back, to Latin 'spuma' (foam) and Sanskrit 'phena,' all bubbling up from a Proto-Indo-European root for sea-spit and froth. A very old word for a very fleeting thing.
