Etymology 1

From Middle English delaien, borrowed from Anglo-Norman delaier, Old French deslaier, from des- + Old French laier (“to leave”), a conflation of Old Frankish lattjan ("to delay, hinder"; from Proto-Germanic latjaną (“to delay, hinder, stall”), from Proto-Indo-European leh₁d- (“to leave, leave behind”)), and Old Frankish laibijan ("to leave"; from Proto-Germanic laibijaną (“to leave, cause to stay”), from Proto-Indo-European leyp- (“to remain, continue”)). Doublet of dally. Akin to Old English latian (“to delay, hesitate”), Old English latu (“a delay, a hindrance”), Old English lǣfan (“to leave”). More at let (to hinder), late, leave.

Etymology 2

From Middle English delaien, from Old French delaiier, a variant of delaissier.
