💡 Grammar Points

Making it Match

As an adjective, 'bajo' changes to match the person or thing it describes. Use 'baja' for feminine things, 'bajos' for plural masculine, and 'bajas' for plural feminine. (e.g., la mesa baja, los techos bajos, las sillas bajas)

❌ Common Pitfalls

Height vs. Length

Mistake: "El lápiz es bajo."

Correction: El lápiz es corto. Use 'bajo' for height (like a person or a building) and 'corto' for length (like a pencil or a story).

⭐ Usage Tips

More than just height

Remember 'bajo' isn't just for height. It's great for describing levels, like 'azúcar bajo' (low sugar) or sound, like 'música baja' (quiet music).

💡 Grammar Points

Always Stays the Same

When 'bajo' means 'under', it's a preposition. This means it never changes. It's always just 'bajo', no matter what word comes after it.

❌ Common Pitfalls

'Bajo' vs. 'Debajo de'

Mistake: "El libro está bajo de la mesa."

Correction: El libro está bajo la mesa. While 'debajo de' needs the 'de', 'bajo' does not. Think of 'bajo' as a one-word version of 'debajo de'.

⭐ Usage Tips

Abstract Ideas

You can use 'bajo' for more than just physical locations. It's perfect for abstract ideas like being 'bajo la ley' (under the law) or acting 'bajo mi responsabilidad' (under my responsibility).

A Form of 'Bajar'

'Bajo' is the present-tense 'yo' (I) form of the verb 'bajar'. You use it to say 'I go down', 'I lower', or 'I download'.

⭐ Usage Tips

Drop the 'Yo'

In Spanish, you can often leave out 'yo' (I) because the '-o' ending on 'bajo' already tells you who is doing the action. Saying 'Bajo en la esquina' is perfectly natural.
