Gender in Spanish Grammar – What You Need to Know

Warning! English speakers! Spanish grammar has two genders, masculine and feminine. It is super important to learn about the gender concept, because all connected words will change to match it. Some words have a gender, others don’t.
How do you say gender in Spanish?
The English word for gender is translated “género” in Spanish grammar. Here are some more Spanish words you’ll need to talk about Spanish gender:
The Genders in Spanish
— género — gender
— sustantivo — noun
— nombre — noun
— masculino — masculine
— feminino — feminine
Grammar gender or lexical gender has nothing to do with being male or female, usually. Nouns are randomly assigned one gender, either masculine or feminine. This applies to every person, place, thing, event or idea. Also, other words carry gender marks too.

Spanish Gender Rules
Like most Spanish grammar concepts, gender has its own set of rules and exceptions. The most important rules are labelling words masculine or feminine and gender agreement.

Why does Spanish have gender?
The only rock-solid noun gender rule is:
Masculine and Feminine in Spanish
Every noun is masculine or feminine. Adjectives, pronouns and verbs pick up their gender from the noun they connect with. Best practice is to learn the gender of nouns for all new words. The easiest way is to look the word up in the dictionary.
Noun Gender
Every noun is either masculine or feminine. This label is randomly assigned. At times it does match the gender of humans and animals. Some do follow a pattern of ending with the suffix -o or -a.
On the other hand the exceptions are numerous. Here are some noun examples that follow the rules.
Masculine Words in Spanish
Identified with the article “el” or “los”. Some masculine nouns end in -o, -ma.
— tiempo — time
— coche — car
— vestido — dress
— libro — book
Feminine Words in Spanish
Identified with the article “la” or “las”. Some feminine nouns end with suffix -a, -tad, -tud, -dad, -ción, -sión, -ción or -umbre.
— pared — wall
— hora — hour
— persona — person
— vacación — vacation
A few general rules can help you identify whether a noun is masculine or feminine. However, it’s best to verify gender accurately with a dictionary.
Gender Agreement in Sentences
Nouns determine the gender and number of other connected parts of speech, such as articles, adjectives, pronouns and verbs.
Article (Determiner) Gender
There are four determiners all have carry the gender from the noun.
Definite articles gender
— el — the, masculine singular
— la — the, feminine singular
— los — the, masculine plural
— las — the, feminine plural
Gender Neutral Article
— lo — the, gender neutral (used with adjectives)
The articles are a special kind of adjective. The gender and number of the article match the noun it describes.
Adjective Agreement
An adjective describes a noun.
— adjetivo — adjective
How does gender and number effect an adjective?
An adjective matches the gender and number of the noun it describes. Here are examples of adjective gender agreement:
— el hijo contento — the happy son
— la hija contenta — the happy daughter
— los hijos contentos — the happy sons
— las hijas contentas — the happy daughters
As you can see, in each of these examples the gender and number of the noun effects the gender and number of the adjective. However, some adjectives stay the same for both. There are exceptions.
Pronoun Gender
A pronoun replaces a noun to avoid repetition. Unlike the other parts of speech, it has a third gender called neuter.
— Neutro — neuter
Gender Neutral Pronouns
— lo — it
— ello — it
— esto — this
— eso — that
— aquello — that
Lists of Masculine and Feminine Spanish Nouns
Within the noun gender concept, two groups exist – biological gender and randomly assigned gender. Specific examples of masculine and feminine nouns are listed.
Biological Gender
In contrast, humans and animals biological gender coincides with the lexical gender. Males are masculine. Females are feminine. They are distinguished as follows:
Male and female in Spanish
— varon — male, masculine
— hembra — female, feminine
Human Biological Gender
Masculine
- el hombre
- niño
- anciano
- jefe
- presidente
Feminine
- mujer
- niña
- anciana
- jefa
- presidenta
Above, the biological gender determined the grammatical gender. In some cases, an entirely different word is used for each gender. Otherwise, the suffix changes for masculine or feminine endings.
Animal Biological Gender
Masculine
- gato
- gallo
- toro
- caballo
Feminine
- gata
- gallina
- vaca
- yegua
Two things happen. First, some animals change the suffix. Second, some animals have two are completely different words between male and female.
Common Nouns
With this special group, both male and female use the exact same word. The gender is only identified by a connected word (a determiner). These labels carry the gender. Here, the label is an article (el or la):
Masculine
- artista
- bebé
- joven
- testigo
- idiota
- tigre
Feminine
- artista
- bebé
- joven
- testigo
- idiota
- tigre
Epicene Nouns
Unlike others, this group uses the same word and gender label for both genders.
All are masculine
- rata
- águila
- ratón
- avestruz
That’s right, even females have the masculine label. After all, who really know whether that rat is male or female? The gender is generalized and defaults to masculine.
Noun gender exceptions
To show how wacky the gender assignments are, here is a list of nouns that don’t follow the rules:
Masculine
- vestido
- mapa
- amor
- día
Feminine
- fortaleza
- mano
- radio
- foto
As you can see, the masculine and feminine traits are irrelevant for gender assignment. There are some patterns with word endings and some rule breakers. That’s why it’s best to remember the only rock-solid rule and strategy #1 below.
Ambiguous Nouns
Plus, some nouns have two genders. Each gender has a different meaning. Or one noun can have a different gender for a different geographical region.
Masculine
- capital
- cometa
- pez
- corte
- cura
- mar
Feminine
- capital
- cometa
- pez
- corte
- cura
- mar
Is this noun masculine or feminine?
Let’s start with the most important strategy first:
Strategy #1 Spanish Dictionary Identifies Gender
The only absolutely accurate way to determine noun gender is to use the dictionary.
Every noun is identified by masculine and feminine in dictionary definitions. The abbreviations are m. for masculine and f. for feminine. Here is a sample definition from a Spanish dictionary:

The sample entry below shows a noun that is ambiguous. Cometa has two meanings that change with the gender. For the people with no Spanish reading experience: cometa is a kite or a comet.
Another option is to use an online dictionary. My favorite online dictionary is linguee.com.
Strategy #2 Always Get the Gender
From the start, it is absolutely necessary to learn the gender for every new noun you add to your vocabulary.
As you build your vocabulary with focused effort, the gender is an essential fact to include with the definition. Vocabulary lists or books gather words and arrange them by topic. Usually, they include the article (el or la) with the word to identify gender.
- el is masculine
- la is feminine
Strategy #3 Guess Noun Gender with a Rule
The letter endings are useful to predict the gender of an unknown noun.
The gender rules are not accurate for building vocabulary. But at times they help to make a wholehearted attempt to be grammatically correct.
Noun Gender Rules
By default, nouns are masculine, unless assigned to be feminine.
With this general rule about 96 out of 100 nouns will be correct with this guess. The word’s ending indicates the gender.
Nouns ending with suffix
-o are masculine-a are feminine
Later, for more precision, add these endings:
Masculine nouns end with letters -s-o-n -e-l -ma-r
Feminine nouns end with suffixes -a -ción -sión, -tad, -umbre
These rules are the reason why some nouns are considered exceptions. Truly, the nouns are not exceptions. In fact, the rules are not always reliable. Do not use the word endings to identify gender for new vocabulary. Because you will make errors.
Strategy #4 Study the Rule Breakers
Include noun exceptions in your vocabulary studies.
Since many nouns do not follow the rules, it’s important to learn the unpredictable ones. Here is a list of rule breakers.
Really, these words are nouns with specific genders that existed before rules. However, since they are so different from typical patterns, grammatical errors occur. Train your brain with the correct gender.
