Clad
mid 16th century (in the sense ‘clothe’): apparently from clad1.
wiktionary
From Middle English clad, cladde, cled(e), cledde, past tense and past participle forms of clethen(“(also figurative) to put clothing on, clothe, dress; to provide clothing to; to arm, equip; to cover, envelop; to conceal; to adorn”), [1] from Old English clǣðan (past tense clǣðde, *clædde), [2] probably from clǣþ, clāþ(“cloth; (plural) clothes”), ultimately from Proto-Indo-European *gleh₁y-, *gley-(“to adhere, cling, stick to”).
From Middle English clad(d), cladde, clade, past tense and past participle forms of clathen, clothen(“to put clothing on, clothe, dress”), [3] from Old English clāðian, clāþian(“to clothe”) (past participle ġeclāded, ġeclaðed, ġeclaðod), [2] [4] from clāþ, clǣþ(“cloth; (plural) clothes”); see further at etymology 1.
Apparently derived from clad(adjective); [5] see etymology 2. Uses of clad as the simple past and past participle form of clad are indistinguishable from uses of the word as the simple past and past participle form of clothe.
