💡 Grammar Points
Adjective Agreement
'Malos' is used when describing masculine things that are plural (more than one). If you were describing just one masculine thing, you'd use 'malo' or the shortened form 'mal'.
Placement is Flexible
Like many Spanish adjectives, 'malos' can go before or after the noun. Placing it after ('resultados malos') is more common; placing it before ('malos resultados') often adds emphasis.
⭐ Usage Tips
Shortening Rule
Remember that 'malo' shortens to 'mal' only when it's placed directly before a singular masculine noun (un mal día). This shortening doesn't happen when it's plural ('malos días').

Frequently Asked Questions
Is 'malos' related to the word 'enfermos' (sick)?
Yes, 'estar malo/a' is a common, often informal way to say 'to be sick or ill' in Spain, especially when referring to children. So, 'Ellos están malos' means 'They are sick.' However, in Latin America, 'enfermos' is much more common for this meaning.
When do I use 'malos' versus 'mal'?
'Mal' is the shortened version of 'malo' used only before a singular masculine noun (like 'un mal momento' - a bad moment). 'Malos' is used for ALL plural masculine nouns ('unos malos momentos' - some bad moments). 'Mal' can also be an adverb meaning 'badly' ('canta mal').
