If you made the mistake of saying *Yo soy calor , you would be saying something like, "I am the incarnation of the abstract concept of Heat." This is probably not what you intended to say unless you were in a play involving the elements. So you might want to review the Tener phrases and practice them until it seems natural to say them.
Some other Tener expressions include:
| Tener calor | to be hot |
| Tener cuidado | to be careful |
| Tener éxito | to be successful |
| Tener frío | to be cold |
| Tener ganas de | to feel like..., to have the desire to... |
| Tener hambre | to be hungry |
| Tener interés | to be interested |
| Tener miedo | to be afraid |
| Tener sed | to be thirsty |
| Tener sueño | to be sleepy |
| Tener prisa | to be in a hurry |
| Tener razón | to be right (correct) |
| No tener razón | to be wrong |
| Tengo que estudiar esta mañana | I have to study this morning. |

| Tenemos que hablar con la profesora | We have to speak with the professor. |
| Tienen que ir al hospital | They have to go to the hospital. |

| Tengo veintiún años | I'm twenty-one (years old). |
| Tiene quince años | He's fifteen. |

Don't forget we must use the whole phrase - don't drop the word años . Remember there is a SERIOUS difference between the word año and ano .
