What is the french word when describing a male word?

There isn't a single French word that directly translates to "male word" in the sense of describing a word's grammatical gender as masculine.

However, you can use these phrases depending on the context:

* "Mot masculin" (masculine word) - This is the most direct translation and is used to describe a word that is grammatically masculine in French.

* "Mot de genre masculin" (word of masculine gender) - This is a more formal way of saying the same thing.

* "Mot qui se conjugue au masculin" (word that conjugates in the masculine) - This emphasizes the conjugation of the word, which is often used to indicate its grammatical gender.

Example:

"Le mot 'chien' est un mot masculin." (The word "chien" is a masculine word.)
