ravioli

Ravioli is treated as a mass noun in common English usage, often referring to the dish as a whole rather than individual pieces of pasta. While it is technically a plural form in Italian, English speakers typically use it with singular verbs or treat it as an uncountable entity, similar to how "spaghetti" is used.

To refer to a specific number of these pasta envelopes, speakers use partitive constructions such as "a piece of ravioli" or "three ravioli." Using the word in a countable sense is grammatically acceptable but less frequent in casual dining contexts.
