💡 Grammar Points
Masculine Noun Rule
Even though 'calor' ends in '-or', it is a masculine noun. Always use 'el' before it (el calor).
Feeling Hot: Tener vs. Estar
To talk about feeling hot, Spanish uses the verb 'tener' (to have). You say 'Tengo calor' (I have heat), NOT 'Soy/Estoy caliente'.
❌ Common Pitfalls
Mixing up the feeling and the object
Mistake: "Estoy caliente. (I am hot.)"
Correction: Tengo calor. ('Estoy caliente' usually refers to being sexually aroused, which is usually not what you mean!)
Using 'hacer' incorrectly
Mistake: "El día es calor."
Correction: The correct way to talk about the weather is 'Hace calor' (It makes heat).
⭐ Usage Tips
The Weather Trick
To describe the weather, use 'HACE' (a form of the verb 'hacer') + the noun: 'Hace calor' (It's hot) or 'Hace frío' (It's cold).

Frequently Asked Questions
Why do Spanish speakers use 'tener' (to have) instead of 'estar' (to be) when they feel hot?
This is a key difference between Spanish and English! In Spanish, feelings like heat ('calor'), cold ('frío'), hunger, and thirst are treated as things you 'possess' temporarily, not states you 'are' in. So, you 'have heat' (Tengo calor).
Is 'calor' always masculine?
Yes. Even though many Spanish words ending in -r are feminine, 'calor' is strictly masculine. You must always use 'el calor', 'mucho calor', etc.
