The adjectives "beau," "nouveau," and "vieux" are all examples of adjectives in French. Specifically, they are examples of masculine singular adjectives. In French, adjectives must agree in gender and number with the noun they describe.

To determine the type of adjectives, we need to consider their endings:

1. "Beau" is a masculine singular adjective that means "beautiful" or "handsome." It does not change its form when describing a singular masculine noun.

2. "Nouveau" is also a masculine singular adjective that means "new." However, it changes its form depending on the gender and number of the noun it describes. For example, the feminine singular form is "nouvelle," the masculine plural form is "nouveaux," and the feminine plural form is "nouvelles."

3. "Vieux" is a masculine singular adjective that means "old." Like "nouveau," it changes its form depending on the gender and number of the noun it describes. The feminine singular form is "vieille," the masculine plural form is "vieux," and the feminine plural form is "vieilles."

Remember that in French, the agreement of adjectives with the noun they modify is an essential grammatical rule.
