means A deep, persistent yearning for something or someone, often tinged with the ache of distance or absence.

from From Old English 'langian,' meaning to grow long, to yearn after — built on the same root as 'long' itself. The thread is lovely and intuitive: desire stretches time out, makes the wait feel long, the way an afternoon spent missing someone seems to last forever. The German 'verlangen' (to crave) shares this old Germanic family, where to want and to lengthen were tangled up together.
