means The amount held by a spoon, used loosely as a casual measure of quantity, especially for food or medicine.

from A straightforward compound of 'spoon' plus '-ful,' the same suffix pattern as 'handful' or 'mouthful' — Old English 'spon' originally meant a chip or shaving of wood, since early spoons were literally carved wooden slivers, and '-full' simply meant 'filled with.' No hidden trick here: it's just 'enough to fill a spoon,' a measuring unit born from whatever utensil was already in your hand.
