💡 Quick Rule
Adentro implies motion *into* a place. Dentro describes location *inside* a place.
Think: Adentro = Action (going in). Dentro = Description (being in).
- In many parts of Latin America, they are used interchangeably in casual speech.
- 'Dentro' must be followed by 'de' when specifying a location ('dentro de la casa'). 'Adentro' usually stands alone.
📊 Comparison Table

| Asking a question | ¿Por qué no vienes adentro? | ¿Qué hay dentro de esa caja? | Adentro focuses on the action of coming in. Dentro de focuses on the contents of a specific place. |
