My sibling lives in another city, so we only see each other during holidays.
My brother or sister lives elsewhere, so we meet mainly on holidays.
The term is gender‑neutral and can refer to either a full sibling, half‑sibling, or step‑sibling.
Choose 'sibling' instead of 'brother' or 'sister' when you don't need to specify gender.
When discussing family dynamics, 'sibling' keeps the conversation inclusive of all genders.
From Old English 'sibb' meaning 'kin, relative' + diminutive suffix '-ling', originally meaning 'a person of kin'.
Use 'sibling' when gender is irrelevant or when referring to both brothers and sisters collectively.
