The word for ‘intelligent’ in Spanish is inteligente. This adjective is used to describe someone who has a high level of mental capability or understanding. It applies to both genders, so you can use it when referring to a man or a woman.
For example, you could say:
- Él es muy inteligente (He is very intelligent).
- Ella es muy inteligente (She is very intelligent).
In Spanish, adjectives generally have to agree with the noun they modify in gender and number, but ‘inteligente’ remains the same in both masculine and feminine forms.
