Frutta vs. frutto
In Italian, both frutta and frutto translate to fruit in English, but they are not interchangeable. The key difference lies in whether you are talking about fruit as a general food category or as individual, countable items.
Frutta
A1Frutta is a feminine singular collective noun. It is used to refer to fruit in a general and uncountable sense, as a food category, a course in a meal (like dessert), or a collection of different types of fruit. It does not have a plural form.

(I like to eat fruit after dinner.)

Frutto
A2Frutto is a masculine singular noun (plural: frutti). It refers to a single, individual, countable piece of fruit, often in a botanical or scientific context. It is also very commonly used in a figurative sense to mean the result, outcome, or product of something, like an effort or a collaboration.

Summary
In short, use frutta (uncountable) when you are talking about fruit as a general food group or a serving, like what you would buy at the supermarket or eat for dessert. Use frutto (countable, plural frutti) when you are referring to a single, specific piece of fruit or when using the word figuratively to mean the result or outcome of an action.
