Introduction
In English, brother-in-law can refer to several different people. It can mean your sister’s husband, your spouse’s brother, or even the husband of your spouse’s sibling in certain family situations. Because English uses one general term for these relationships, Spanish can sometimes feel a little confusing at first.
The key point is that Spanish has specific words for family members, and the correct translation depends on gender, relationship, and context. If you are learning Spanish for travel, family conversations, school, or real-life communication, understanding cuñado and hermano político is very useful.
No fluff here — just what actually works.
Direct Translation: Brother-in-Law in Spanish
The most common Spanish translation for brother-in-law is:
- cuñado — brother-in-law, masculine singular
- cuñados — brothers-in-law, masculine plural or mixed group
In everyday conversation, cuñado is the go‑to term when you want to refer to your sister’s husband or your spouse’s brother. Because the word is masculine, you’ll hear it paired with male pronouns: Mi cuñado works in marketing, *¿Cómo está tu cuñado?Here's the thing — * is a common greeting among relatives. When more than one brother‑in‑law is present, the plural cuñados covers both all‑male groups and mixed‑gender gatherings; for example, Los cuñados de la familia se reunieron en la boda.
The feminine counterpart, cuñada, designates a sister‑in‑law (your brother’s wife or your husband’s sister). The plural cuñadas follows the same pattern. Using the gender‑specific forms shows attention to detail and helps avoid ambiguity, especially in written communication such as emails or official forms.
When a more formal or explanatory tone is required — say, in a legal document, a family tree, or a conversation with someone unfamiliar with the informal shorthand — hermano político is preferred. Now, this phrase literally means “political brother,” emphasizing the tie created by marriage rather than blood. It is gender‑neutral in the sense that hermano político can refer to a male or female relative by marriage, though the accompanying article (el or la) will indicate gender Small thing, real impact. Practical, not theoretical..
Regional nuances also affect choice. In many Latin American countries, cuñado dominates casual speech, while in Spain you might hear hermano de mi esposa or hermano de mi hermana when clarity is needed. Some areas, particularly in the Caribbean, use cuñao as a colloquial, affectionate shortening of cuñado, but this is informal and not appropriate in formal contexts Easy to understand, harder to ignore. No workaround needed..
To illustrate the difference, consider these example sentences:

- Las cuñadas de la familia se organizaron para la fiesta. (The sisters‑in‑law organized the party.)
Understanding when to use cuñado versus hermano político hinges on context: informal chats, family gatherings, and casual writing favor cuñado; formal letters, legal paperwork, or situations where the marital connection must be explicit call for hermano político.
