What is an Italian invariable adjective?

An invariable adjective in Italian is an adjective that does not change its form to agree with the gender or number of the noun it modifies. This is different from most adjectives in Italian, which do change to agree with the noun.

Here are some examples of invariable adjectives in Italian:

* solo (alone)

* intero (whole, entire)

* stesso (same)

* molto (very)

* poco (little)

* tanto (much, many)

* diverso (different)

* bello (beautiful - when used as an exclamation)

It is important to note that:

* Some invariable adjectives can function as adverbs when placed before a verb. For example, "parla *molto* velocemente" (he speaks *very* quickly).

* The adjective "bello" can be variable when used as an adjective describing a noun. For example, "una bella ragazza" (a beautiful girl).

While invariable adjectives can seem less common than variable adjectives, they are still important to recognize and understand for proper Italian grammar.
