Is 'eleve masculine or feminine

Answer 1

The word "enfant" is both a masculine and a feminine in French, so you can write "un enfant" for a boy (or even a girl) or "une enfant" (for a girl only). The plural "les enfants" could be both feminine and masculine, but it is very likely that the vast majority of French speakers understand it as masculine, the masculine being also the mode you use in French when being "unspecific" about the gender.
