Usage notes
One sometimes encounters the spelling, which may seem appropriate given the spelling of the root word. However, that word derives from the Latin ; its spelling with -ce reflects its modern French pronunciation while conceding to the standard orthography of modern French, in which the -uce represents where the spelling -ute — closer to the Latin spelling — would represent. As the sequence -tia- is usually read as in contemporary French, the spelling of  is able to follow the form of the Latin etymon while remaining in accord of normative French orthography.
