From Middle English relai (“fresh team of dogs for a hunt”) (compare Middle English relaien (“to relay”)) from Middle French relai (“reserve pack of hounds”), from relaier (“to exchange tired animals for fresh”); literally, "to leave behind", from Old French relaier (“to leave behind”), from re- + laier (“to leave”), of Germanic origin--a conflation of Frankish *latjan (“to delay, hinder”) (from Proto-Germanic *latjanan (“to delay, hinder, stall”) from Proto-Indo-European *le(i)d- (“to leave, leave behind”)) and Frankish *laibjan (“to leave”) (from Proto-Germanic *laibijanan (“to leave, cause to stay”) from Proto-Indo-European *leip- (“to remain, continue”)). Akin to Old English latian (“to delay, hesitate”) (from Old English latu (“a delay, a hindrance”)), Old English lǣfan (“to leave”). More at let, leave.
