One Version for Everyone

In Spanish, describing words that end in '-l' are 'gender neutral.' This means 'racional' stays exactly the same whether you are describing a man, a woman, or a gender-neutral object.

Making it Plural

To make 'racional' plural, you don't just add an '-s.' Because it ends in a consonant, you must add '-es' to get 'racionales.'

Avoid 'Racionala'

Mistake: “Una mujer racionala.”

Correction: Una mujer racional. (The word doesn't change to an 'a' for feminine nouns.)

razonable

rah-thoh-NAH-bleh (Spain) / rah-soh-NAH-bleh (L. Am.)raθoˈnaβle

adjectiveB1general
Use 'razonable' when describing a person's attitude, behavior, or an idea as sensible, fair, or moderate.
A simplified cartoon figure successfully placing the final block on a stable, perfectly balanced structure, indicating a sensible and well-thought-out approach.

Examples

Su explicación sobre el retraso fue muy razonable.

His explanation for the delay was very sensible.

Necesitamos llegar a un acuerdo razonable para ambas partes.

We need to reach a reasonable agreement for both parties.

Agreement

Since 'razonable' ends in -e, it stays the same whether the noun is masculine (el acuerdo razonable) or feminine (la propuesta razonable). Just add -s for plural.

Confusing with 'Rational'

Mistake: “Using 'racional' when you mean 'sensible' or 'fair price'.”

Correction: 'Racional' usually refers to thinking process or math. Use 'razonable' for fairness and general sensibility.

Lógico vs. Racional vs. Razonable

Learners often confuse 'lógico' and 'racional' as they are very similar. Remember that 'lógico' often implies an outcome that makes sense, while 'racional' is more about the process of thinking. 'Razonable' is distinct, usually describing something as sensible or fair.
