Etymology
From Middle English areynen (“to interrogate, arraign, reprimand”), from Anglo-Norman areiner, arener, from Old French araisnier, areisnier, aresnier (“to speak to, address; accuse (in a law court)”) (whence modern French arraisonner (“to verify cargo, to arraign”)), from Vulgar Latin *arratiōnāre, from Latin adratiōnāre, from ad (“to”) + *ratiōnāre (“to reason, talk reasonably, talk”), from ratiō (“reason, reasoning, discourse”), from rat-, past-participle stem of rērī (“to reckon, calculate”). First attested in the late 14th century. Doublet of areason.
