Definition of brother-in-law in English
The most common translation for “cunhado” in English is “brother-in-law”.
This term is formed by combining “brother” with “in-law”, indicating the relationship acquired by marriage. Using “in-law” is the standard for designating in-laws in English.
English allows for clarity in family relationships. Mastering these expressions opens doors to more fluent and natural conversations about family, routine, and personal connections.
On your English journey, understanding how to refer to family members strengthens your communication and expands your possibilities for interaction.
How to use brother-in-law in English in practice
You will use brother-in-law when talking about your sister's husband or your spouse's brother. For example:
My brother-in-law is visiting us this weekend. Meu cunhado vai nos visitar neste fim de semana.
In the professional environment, it may come up in presentations or informal conversations:
I went to the event with my brother-in-law. Fui ao evento com meu cunhado.
In informal situations, the clarity of this term helps you to position yourself with confidence in different social contexts.
When to use (and when not to use) "cunhado" in English
Always use brother-in-law whenever you need to refer to your brother-in-law in English, both in formal records and in everyday conversations.
Avoid using just “brother” for brother-in-law, as this can cause confusion. “Brother-in-law” makes it clear that the relationship is by marriage, not by blood.
If you are talking about other family members by marriage, follow the same pattern: sister-in-law for sister-in-law, mother-in-law for mother-in-law.
The clarity of these terms facilitates interactions on trips, family reunions, or professional situations. This is how confidence is built.
