💡 Grammar Points
Using 'Tener' for Interest
Unlike English, which uses the verb 'to be' (I am interested), Spanish uses 'tener' (to have): 'Yo tengo interés'. Remember to say 'have interest' when you talk about being curious.
❌ Common Pitfalls
Don't confuse the noun and the adjective
Mistake: "Soy intereso en el cine. (Incorrect verb form)"
Correction: Tengo interés en el cine. (I have interest in cinema.) The word 'interesado' is the adjective for 'interested'.

Frequently Asked Questions
Since 'interés' ends in -s, why is it masculine ('el interés')?
Nouns that end in consonants in Spanish are typically masculine, and 'interés' follows this rule. Even though it ends in -s, it is treated like any other masculine noun ending in a consonant, such as 'el árbol' or 'el motor'.
When do I use 'interés' versus 'interesante'?
'Interés' is a person, place, or thing (a noun), referring to the feeling itself ('Tengo interés' - I have the feeling). 'Interesante' is a describing word (an adjective), referring to what causes the feeling ('El libro es interesante' - The book is the cause).
