Yearning
Old English giernan, from a Germanic base meaning ‘eager’.
wiktionary
From Middle English yerning, from Old English ġierning, ġierninge. Equivalent to the gerund ( yearn + -ing). yearn comes from Proto-West Germanic *girnijan, from Proto-Germanic *girnijaną, from *gernaz(“eager, willing”) + *-janą, from Proto-Indo-European *ǵʰer-(“to yearn for”).
From earlier yerning, from Middle English yernyng, erning, renning. From Old English rynning and gerunnen, geurnen(“run together, coagulated, curdled”), past participles of gerinnan, geirnan, respectively. Influenced by Middle English yern(“to (cause to) coagulate or curdle”), Old English iernan(“to run, flow”), metathesized forms derived from the same origin. From verbal prefix ge- + rinnan(“to run”). First element is from Proto-West Germanic *ga-, from Proto-Germanic *ga-, from Proto-Indo-European *ḱóm(“with, by”); second element is from Proto-Germanic *rinnaną, from Proto-Indo-European *h₃r̥-néw-ti, from *h₃er-(“to move”). Doublet of rennet, run.
