💡 Grammar Points
Shortening 'malo' to 'mal'
When 'malo' comes right before a masculine word, it shortens to 'mal'. For example, you say 'un mal día' (a bad day), not 'un malo día'.
Matching the Noun
Like most adjectives, 'malo' changes to match the thing it describes: 'malo' (masculine singular), 'mala' (feminine singular), 'malos' (masculine plural), and 'malas' (feminine plural).
❌ Common Pitfalls
Forgetting to shorten to 'mal'
Mistake: "Tengo un malo presentimiento."
Correction: Tengo un mal presentimiento. (I have a bad feeling.) Remember to drop the '-o' before a single masculine thing.

💡 Grammar Points
Using 'ser' vs. 'estar'
'Ser malo' describes a permanent quality, like a person's character ('Él es malo' - He is an evil person). 'Estar malo' describes a temporary state, like spoiled food ('La leche está mala') or being sick ('Estoy malo').
❌ Common Pitfalls
Mixing up 'ser' and 'estar'
Mistake: "La sopa es mala."
Correction: La sopa está mala. If you mean the soup has gone bad, use 'estar'. Saying 'es mala' suggests the recipe itself is fundamentally bad.

Frequently Asked Questions
What is the real difference between 'mal' and 'malo'?
'Malo' is the standard adjective. 'Mal' is just a shorter version of 'malo' that you must use when it's placed directly before a masculine, singular noun. Think of it like 'a' vs 'an' in English. For example, 'un mal coche' (a bad car), but 'el coche es malo' (the car is bad).
Can 'malo' mean 'sick'? I thought that was 'enfermo'.
Yes, it can! Using 'estar malo/a' is a very common and slightly more general way to say you are sick or unwell, especially in Spain. 'Estar enfermo/a' is also perfectly correct and maybe a little more specific. You can use both!
If I say 'Él es malo,' does that mean he's evil or just not a good person?
It can mean both, and you'd know from the context. It usually implies a strong negative judgment about his character. It could mean he's mean, unkind, or genuinely evil like a movie villain. It's a stronger statement than saying he's just 'not nice'.
