The Primary Translation: "Inmaduro" and "Inmadura"
The adjective "inmaduro" comes directly from the Latin roots in- (not) and madurus (mature, ripe). It functions exactly like its English counterpart, describing both biological immaturity (e.Even so, g. , fruit that hasn't ripened) and psychological or emotional immaturity.
- Masculine singular: inmaduro
- Feminine singular: inmadura
- Masculine plural: inmaduros
- Feminine plural: inmaduras
Examples:
- El niño es muy inmaduro para su edad. (The boy is very immature for his age.)
- Esa fruta está inmadura, no la comas. (That fruit is immature/unripe, don't eat it.)
- Sus ideas son inmaduras. (Their ideas are immature.)
Pronunciation tip: Inmaduro is pronounced roughly "een-mah-DOO-roh" with the stress on the second-to-last syllable. The double "m" is pronounced as a single, slightly lengthened "m" sound—not like in English "immature" where the double "m" is separated by a syllable break Took long enough..
Expanding Your Vocabulary: Synonyms and Near-Synonyms
While inmaduro is the go‑to word, Spanish offers a rich palette of related terms that convey shades of immaturity. Using them correctly can make your speech sound more natural and precise.
"Infantil" — Childish or Infantile
"Infantil" is often used to describe behavior that is typical of a much younger child. It can be neutral (referring to childhood) or negative (implying a lack of maturity).
- Dejó de llorar por un juguete; eso es muy infantil. (He stopped crying over a toy; that's very childish.)
- La película tiene un humor infantil. (The movie has childish humor.)
Note: In some contexts, infantil can also mean "for children" (e.g., literatura infantil = children's literature). When used critically, it's stronger than inmaduro because it directly evokes the behavior of a small child.
"Pueril" — Puerile (Formal/Literary)
"Pueril" comes from Latin puer (boy) and is often used in formal or written contexts to describe something silly, trivial, or immature in a dismissive way Worth knowing..
- Sus comentarios pueriles arruinaron la reunión. (His puerile comments ruined the meeting.)
- Es una actitud pueril e irresponsable. (It's a puerile and irresponsible attitude.)
This word is less common in everyday conversation but valuable for advanced learners.
"Verde" — Green or Unripe (Figurative)
"Verde" literally means green. When applied to people, it can mean "young and inexperienced" or, in some contexts, "immature" (especially in Latin America).
- Este empleado todavía está muy verde. (This employee is still very green/immature.)
- Él es muy verde para ese puesto. (He's too green/immature for that position.)
Be careful: verde also has slang meanings related to sexual innuendo (chiste verde = dirty joke). Context usually disambiguates.
"Niño/a" — Literally "Child," Used as an Adjective
Calling someone a niño or niña as a description can be a harsh way to call them immature.
- No seas niña, acepta la crítica. (Don't be a child / Don't be immature, accept the criticism.)
- Actúa como un niño pequeño. (He acts like a little kid.)

- Spain: Inmaduro is universally understood. Infantil is very common. Pueril is used in educated speech.
- Mexico and Central America: Inmaduro dominates. Bebé (baby) or chiquito/a (little one) can be used mockingly.
- Argentina and Uruguay: Inmaduro and infantil are standard. Verde for "green/inexperienced" is common.
- Caribbean Spanish: Inmaduro is standard. Slang like pendejo (often meaning "fool" or "jerk") can imply immaturity but is very strong.
How to Use "Immature" in Different Contexts
Mastering how to say immature in Spanish means knowing which word fits which situation. Here’s a breakdown by scenario Simple, but easy to overlook..

When talking about someone's emotional development or childish reactions, inmaduro and infantil are your best choices.
- Su reacción fue muy inmadura. (Their reaction was very immature.)
- Deja de ser infantil y habla con seriedad. (Stop being childish and talk seriously.)
Use pueril for more formal criticism, such as in a business review or academic discussion.

When referring to someone who is simply young or not yet fully developed (without negative judgment), joven (young) is usually better. Inmaduro carries a critical tone Turns out it matters..
- Correct neutral: Es un joven inexperto. (He's an inexperienced young person.)
- Negative: Es un joven inmaduro. (He's an immature young person—implies a flaw.)
In Work or Professional Settings

Common Mistakes to Avoid
1. False Cognate: "Immature" in English vs. "Inmaduro" in Spanish
Spanish inmaduro is spelled with only one "m" in the first syllable, while English "immature" has two. Don't accidentally write immaduro (with double "m" at the start) — that's a common spelling error among English speakers.
2. Overusing "Inmaduro" for All Contexts
As we've seen, inmaduro covers both fruit and behavior. But using it for everything can sound robotic. Mix in infantil for childish behavior, verde for inexperience, and pueril for formal writing.
3. Gender Agreement Mistakes
Always match the adjective to the gender of the noun. So una niña inmadura (feminine). Also, for example, un niño inmaduro (masculine) vs. For mixed groups, use the masculine plural inmaduros.
4. Confusing "Inmaduro" with "Maduro" (Ripe, Mature)
Maduro means both "mature" and "ripe." So una persona madura is a mature person, and un plátano maduro is a ripe banana. The negative form inmaduro flips both meanings.
