When you start learning Spanish, you quickly learn a basic rule: nouns referring to men usually end in -o, and nouns referring to women end in -a. However, there is a large group of words that breaks this rule completely.
Nouns ending in -ista that describe people have the exact same form for both men and women. Words like artista, dentista, and periodista will always end in -a, regardless of who you are talking about. English speakers often trip over this and try to invent masculine versions, but keeping the ending unchanged is essential for sounding natural in Spanish.
To specify if the person is a man or a woman, you only change the articles and the adjectives around the noun. You use el for a man and la for a woman, but the noun itself stays exactly the same. You will never change the final letter of the noun.
La periodista entrevistó al dentista.
(The female journalist interviewed the male dentist.)
Él es pianista y ella es violinista.
(He is a pianist, and she is a violinist.)
Professions and hobbies
This pattern is incredibly common for professions, hobbies, and lifestyles. For example, musicians like a guitarrista or a baterista use this form. The same goes for athletes like a futbolista, a ciclista, or a velocista. The general word for an athlete, deportista, follows this exact rule as well.
It also applies to many everyday jobs and roles. You might speak to a recepcionista, hire an electricista, or take a ride with a taxista.
El taxista me ayudó con las maletas.
(The male taxi driver helped me with the suitcases.)
La nueva futbolista marcó un gol increíble.
(The new female footballer scored an incredible goal.)
Llamamos a un electricista para reparar las luces.
(We called a male electrician to repair the lights.)
Beyond professions
Not all -ista words are jobs. The rule applies to anyone described by a word with this ending. A turista visiting your city, an activista fighting for a cause, or the protagonista of a novel all share this ending. Even less desirable titles like a carterista or a contrabandista work exactly the same way.
El museo está lleno de turistas.
(The museum is full of tourists.)
Ella es la protagonista de la película.
(She is the protagonist of the film.)
Un carterista robó mi dinero en el metro.
(A male pickpocket stole my money in the subway.)
Watch out
English speakers often feel tempted to change the ending to an -o when talking about a man. Remember that words like periodisto or turisto do not exist in Spanish. You must keep the -a.
There is one notable exception to this strict rule. For the word modista, you will sometimes hear the masculine form modisto to refer to a male fashion designer. This is widely accepted in modern Spanish. But for almost every other word in this group, the -ista remains frozen.
Mi hermano es un economista brillante.
(My brother is a brilliant economist.)
El famoso modisto presentó su nueva colección.
(The famous male fashion designer presented his new collection.)
Summary
Whenever a noun describing a person ends in -ista, it stays exactly the same for both masculine and feminine forms. Just change the article to el or la to show gender, and never change the ending to an -o.
