Turmeric (which many Americans, at least, misspell as tumeric) has had many forms over the years. The 16th century had tarmaret, tormarith, tormarthe,tormerik, tormeryke, turmirick, 16th-17th centuries: turmericke, 17th century: turn-merick, turmerocke, turmerack, termarcke, tarmanick,tarmaluk, 17th-19th centuries: turmerick, 18th century to present: turmeric. Note that the first r appears in all versions, so none of you anti-curmudgeons can claim that tumeric is correct! As for the etymology of this word, it is somewhat obscure. The most popular (and perhaps most likely) explanation is that it derives from the French terre mérite or Latin terra merita "worthy earth", apparently an early term of commerce for the spice, referring to the earth in which the root is found or grown.
