In everyday spoken and written French, the most natural way to express the concept of 'siblings' is to use the phrase frères et sœurs (brothers and sisters) rather than a single noun.
Which one should you use?
While English has the gender-neutral noun 'sibling', French speakers almost always default to the gender-inclusive plural frères et sœurs to refer to one's siblings.
Is there a formal and an informal way to say it?
The term adelphe is highly formal, technical or literary and is rarely used in casual conversation. In contrast, if you want to refer to a brother or sister informally, you can use frangin for brother and frangine for sister.
Did you know?
- The word germain can describe a full sibling, coming from the Latin germānus meaning 'from the same germ' or 'seed'.
