means A deep, persistent longing for something or someone, often tinged with sadness or distance.

from From Old English 'giernan' (to strive, desire, yearn), tied to 'georn' meaning eager or desirous. It's a cousin to German 'gern' (gladly, willingly) and traces back to a Proto-Germanic root for eagerness and craving — the same ancient pull that once meant simply 'to want badly' has, over centuries, softened into something more ache than appetite.
