   Lasagna vs. lasagne

   For the flat, wide pasta and the dish made from such pasta, North American English speakers use lasagna. English speakers from outside North America use lasagne. Other than the spelling, there is no difference between the words in English.
   The word comes from Italian, of course. In that language, lasagna is the singular noun and lasagne is the plural. The word first appeared in English in the 19th century, but the dish did not become popular in English-speaking countries (the U.S. first, then elsewhere) until the second half of the 20th century.
