old

The French word 'vieux' is the masculine singular form of 'old' and is used to describe male nouns or people. It can refer to age, as in an elderly person, or it can describe something that has been around for a long time, such as an antique or a well-established tradition. In the feminine singular, 'vieux' becomes 'vieille', and in the plural, it becomes 'vieux' for masculine nouns and 'vieilles' for feminine nouns. It is also worth noting that 'vieux' can have a pejorative connotation when used to describe people, implying that they are outdated or past their prime, so it should be used with care in social contexts.
