The cello is also commonly referred to by its full name, violoncello, or simply as the "cello." The term "violoncello" is of Italian origin and is a combination of "violin" (small) and "cello" (big), indicating that it is a larger, lower-pitched instrument compared to the violin.

In informal settings or conversations, musicians might simply use the term "cello" to refer to the instrument. Additionally, colloquial terms like "cello" or "the big fiddle" are sometimes used, especially in non-formal contexts. However, "violoncello" or "cello" are the most widely accepted and recognized names for this string instrument.
