Origin of hele
From Middle English helen, helien, from Old English helan (“to conceal, cover, hide”, strong verb) and helian (“to conceal, cover, hide”, weak verb), from Proto-Germanic *helaną (“to conceal, stash, receive stolen goods”), *haljaną (“to hull, conceal”), both from Proto-Indo-European *kel- (“to hide”). Cognate with Scots heal (“to cover, hide, conceal”), Eastern Frisian hela (“to conceal”), Dutch helen (“to conceal”), German hehlen (“to conceal”). More at heal.
