Why was "tantrum" trending last week?
late 14c., araynen, "to call to account," from Old French araisnier "speak to, address; accuse (in a law court)," from Vulgar Latin *arrationare, from Latin adrationare, from ad- "to" (see ad-) + *rationare, from ratio "argumentation, reckoning, calculation" (see ratio). Sense of "to call up on a criminal charge" is c.1400. The excrescent -g- is a 16c. overcorrection based on reign, etc. Related: Arraigned; arraigning.
