Basic definitions
Niño means child or boy, referring to age or gender. It can describe any young person, male or sometimes informally gender-neutral when context makes clear. Use niño for boys or children in general.
Hijo means son, indicating a family relationship: the child of a parent. Use hijo when you want to say someone is your son or someone else’s son.
Short comparison
Niño = a child, often focusing on age or whether someone is a boy.
Hijo = a son, focusing on the relationship between parent and child.
Gender and number forms
Niño (singular masculine), plural niños. Feminine form is niña, plural niñas.
Hijo (singular masculine), plural hijos. Feminine counterpart is hija, plural hijas.
Common phrases and examples
Below are practical sample phrases you might hear on signs, in conversations, or on forms. Each Spanish phrase is followed by a simple English explanation.
Phrase: ¿Dónde está el niño?
English: Asking where a child or boy is in a public place.
Phrase: Mi hijo tiene cinco años.
English: Saying my son is five years old; emphasizes family relationship and age.

Phrase: Este es mi hijo.

Usage in forms and everyday situations
When filling forms that ask for family information, use hijo or hija to indicate relationships: Nombre del hijo means name of the son.
On signs or radio announcements about safety or lost children, you will see niño or niña to describe age or gender rather than family ties: Se busca niño perdido. means a lost child is being sought.
Practical tips for beginners
Tip: If you want to express family relationship, choose hijo/hija. If you are talking about age, play, or a child in general, use niño/niña.
Tip: Use articles and adjectives correctly. For a specific boy use el niño, for a son use mi hijo. Example: El niño es travieso. vs Mi hijo es travieso.
Tip: When addressing someone about their children, you can ask ¿Tiene hijos? to mean do you have children. This is common in forms or polite conversation.
Common beginner mistakes
Mistake: Using niño when you mean son in a family context. Example error: Mi niño vive aquí. This sounds like you are referring to a child in general rather than your son. Better: Mi hijo vive aquí.
Mistake: Using hijo to describe a child in public when not implying family. Example error: El hijo juega en el parque. This implies that the boy is someone’s son; better: El niño juega en el parque.
Mistake: Forgetting agreement in gender and number. Example error: Mi hijos son inteligentes. Correct: Mis hijos son inteligentes.
