In Spanish, family members are called familiares or parientes, and the immediate family word set covers madre (mother), padre (father), hermano (brother), hermana (sister), hijo (son), and hija (daughter). Spanish organizes most family vocabulary around a male and female ending pair, so once you learn the pattern for one relative, several others follow the same rule. This guide covers every common Spanish family word, including the trickier extended family and in-law terms that textbooks often skip.
Short answer: The core Spanish family words are madre (mother), padre (father), hermano or hermana (brother or sister), hijo or hija (son or daughter), and abuelo or abuela (grandfather or grandmother). Spanish has more than 30 distinct family terms once you add aunts, uncles, cousins, and in-laws, and almost all of them follow a simple -o or -a gender pattern.
Start with the words you will use most. These six cover parents, siblings, and children, and they appear in nearly every conversation about family in Spanish.
Notice that each pair shares a root and swaps only the final vowel: hermano becomes hermana, hijo becomes hijo. Once that pattern clicks, roughly half of all Spanish family vocabulary becomes predictable rather than something you have to memorize word by word. You can practice these words inside full sentences and real scenes, rather than as an isolated list, using Noun Town's language learning game, which places vocabulary like this directly into everyday 3D environments with native speaker audio.
One quirk worth flagging early: the plural masculine form often stands in for a mixed group. Los hijos can mean "the sons" or "the children" (sons and daughters together), depending on context. The same rule applies further down this list, so it is worth getting comfortable with it now.
Extended family vocabulary in Spanish follows the same -o and -a gender pattern as the immediate family words above, which makes it easier to pick up than it first looks.
Aunt and uncle in particular get searched often by English speakers learning Spanish, and it is easy to see why: tio and tia do not resemble their English equivalents at all, unlike hermano or madre, which at least share some sound logic with English through shared Latin roots further back. There is no shortcut here beyond repetition, ideally in context rather than on a flashcard, since a sentence like "mi tio vive en Madrid" (my uncle lives in Madrid) gives the word a place to anchor in memory.
Cousin works slightly differently from English. Spanish does not distinguish between a first cousin and a more distant one in everyday speech. Primo or prima covers the relationship generally, and you would only specify "primo segundo" (second cousin) in a conversation that actually needed that level of detail, which in practice is rare.
In-law and step-family terms are where most intermediate Spanish learners get stuck, mainly because English in-law vocabulary (mother-in-law, son-in-law) does not map onto Spanish word-for-word.
Yerno and nuera are the two words that trip people up most, since neither one contains a recognizable root the way suegro or cunado does. If it helps, yerno has no close English cousin at all, so it is worth treating as a standalone vocabulary item rather than trying to derive it from "son" plus a suffix the way the other in-law terms work.

Spanish nouns carry grammatical gender, and family words inherit it directly from the person's actual sex in almost every case: hijo is a son because the noun is masculine, hija is a daughter because the noun is feminine. This is one of the few corners of Spanish grammar where the grammatical gender and the real-world meaning line up neatly, which makes family vocabulary a genuinely good place to build confidence with noun gender more broadly. The same basic concept of grammatical gender appears across the wider Romance language family, as summarized on Wikipedia's overview of grammatical gender.
The pattern breaks slightly at the plural level, and this is the part that trips up English speakers most. Los padres almost always means "parents," not "fathers," even though padre on its own means father. The same logic applies to los hermanos (siblings, not just brothers) and los abuelos (grandparents, not just grandfathers). Spanish defaults to the masculine plural whenever a group is mixed or unspecified, a rule that extends well beyond family vocabulary into Spanish grammar generally. The Real Academia Espanola, Spain's official language authority, documents this masculine-default rule as a standard feature of the language rather than an exception.
If you only remember one rule from this section, make it this one: when a Spanish family word looks masculine but the context is a group rather than one specific person, check whether it might actually mean "everyone in that category" before assuming it excludes women entirely.
Possessive adjectives do most of the heavy lifting once you know the nouns. Mi (my), tu (your), and su (his, her, your formal, their) attach directly to the family word, with no gender agreement needed on the possessive itself.
Tengo dos hermanos y una hermana. (I have two brothers and one sister.)
Mi madre y mi padre viven en Barcelona. (My mother and my father live in Barcelona.)
¿Cuantos primos tienes? (How many cousins do you have?)
Tener (to have) is the verb you will reach for constantly in this topic, almost always in the present tense. Beyond that, most family conversations in Spanish stay fairly simple grammatically, which makes this one of the more approachable vocabulary sets for a beginner to practice speaking out loud early on. Family vocabulary like this usually sits within the A1 to A2 range of the Common European Framework of Reference for Languages (CEFR), the standard used across Europe to describe proficiency levels.
The core vocabulary above is standard across the Spanish-speaking world, and you will be understood everywhere using these words. The differences that do exist are mostly informal and regional rather than a separate set of "correct" words to learn.
None of this regional variation changes the formal words, so if you learn madre, padre, hermano, hermana, abuelo, abuela, tio, tia, and primo or prima first, you will be understood correctly from Mexico to Spain to Argentina. The Instituto Cervantes, Spain's official institute for promoting Spanish language and culture internationally, is a reliable resource if you want to dig deeper into regional vocabulary variation beyond family terms.

Try Noun Town on SteamLa familia. The related word parientes means relatives specifically, while familia can refer to either the people or the household as a whole.
Los padres. Confusingly for English speakers, padres on its own usually means parents rather than fathers. If you need to be precise, la madre y el padre names both separately.
Hermanos. Like padres, hermanos covers brothers and sisters together as a mixed group. A single sister is hermana and a single brother is hermano.
Los abuelos. One grandfather is abuelo and one grandmother is abuela, following the same -o and -a pattern used by most Spanish family words.
Aunt is tia and uncle is tio. Together, a group of aunts and uncles, or an aunt and uncle paired together, is tios.
Primo for a male cousin and prima for a female cousin. A group of cousins, or cousins of mixed gender, is primos.
Suegro and suegra are father-in-law and mother-in-law, yerno is son-in-law, nuera is daughter-in-law, and cunado and cunada are brother-in-law and sister-in-law.
It includes sisters. Spanish defaults to the masculine plural form when a group includes both genders, so hermanos can mean siblings just as easily as it means brothers, and context tells you which.
Most learners pick up the core 15 to 20 family words, covering immediate and extended family, within about a week of short regular practice sessions, since the words repeat the same handful of grammar patterns.
Yes. Noun Town places family vocabulary inside everyday 3D scenes with native speaker audio and spaced repetition, so words like madre or primo get reinforced through contextual recall rather than a flat list to memorize.
