Etymology 1

From Middle English wel, wal, wol, wele, from Old English wel ("well, abundantly, very, very easily, very much, fully, quite, nearly"), from Proto-Germanic \wela, \wala ("well", literally "as wished, as desired"), from Proto-Indo-European \welh₁-* ("wish, desire").

Cognates include Yola vella, waal, wel, well, wull; Cimbrian boll, bóol; Dutch wel; German wohl, wol, woll; Danish, Icelandic, Norwegian Bokmål, and Norwegian Nynorsk vel; Faroese væl; Swedish väl, wäl; and Gothic 𐍅𐌰𐌹𐌻𐌰 (waila). Related to will.

Etymology 2

From Old English wielle, descending through Middle English welle to modern English. The Old English form derives from Proto-West Germanic \wallijā and Proto-Germanic \wallijǭ, meaning well, swirl, wave — a root that carried senses of both the still source and the moving surface. Proto-Indo-European \welH-* underlies it, meaning to turn, wind, roll.

The Germanic cognates preserve different aspects: West Frisian wel, Dutch wel, and German Low German Well keep the well; German Welle has drifted to mean wave; Danish væld holds both well and spring; Swedish väl narrows to a well; Icelandic vella has moved on entirely, now describing boiling, bubbling, eruption. Each language chose which feature of turning water to retain.

Etymology 3

From Middle English wellen, by merger of two Old English verbs: intransitive weallan and transitive wiellan, both meaning "to boil." Each traces separately to Proto-Germanic, wallaną and wallijaną respectively. The result is a doublet of wall.

Cognates survive across Germanic: German wallen ("boil, seethe"), Danish vælde ("gush"), Norwegian Nynorsk vella. Albanian valë ("hot, boiling") preserves an outside connection.
