From Middle English scholde, from Old English sċolde, first and third person preterite form of sċulan (“should,” “have to,” “to owe”), the ancestor of English shall. By surface analysis, shall + -ed. Cognate with German sollte, Gothic 𐍃𐌺𐌿𐌻𐌳𐌰 (skulda), Swedish skulle. Related to Middle English shild and shildy. The loss of /l/ in this word is probably due to weak stress, as in would and could (though in the latter, the /l/ was due to the analogy of the former two).
