The word for ‘pretty’ in French is ‘joli’ when referring to masculine nouns and ‘jolie’ for feminine nouns. For example, you would say ‘un joli garçon’ (a pretty boy) or ‘une jolie fille’ (a pretty girl).
In French, adjectives must agree in gender and number with the nouns they describe, which is why it’s important to use ‘joli’ for masculine subjects and ‘jolie’ for feminine subjects. This structure is a fundamental rule in French grammar, adding a layer of beauty and detail to the language.
