French nouns have a gender. For instance, ‘a chair’ is feminine, and ‘an armchair’ is masculine. The gender of a noun is expressed in the companion article: A or THE in French can be masculine or feminine. For instance, you may say un mode to translate ‘a method’ and une mode to say ‘a fashion’. Therefore, it’s important to memorize the gender of the article with every new noun you learn. You wouldn’t want to serve cat food – pâtée – to your guests instead of pâté.
