Modal verbs are auxiliary verbs that help express the speaker’s attitude, intention, or mood towards the main verb’s action. In Spanish, the primary modal verbs are poder, querer, deber, necesitar, saber, and tener que. Each of these verbs carries a different meaning and can significantly alter the context of a sentence.

Poder: Expressing Ability and Possibility

Poder is used to indicate the ability, permission, or possibility of performing an action. It can be translated as “can” or “may” in English. Here are some examples:

• Yo puedo hablar español. (I can speak Spanish.)
• ¿Puedo ir al baño? (May I go to the bathroom?)

Querer: Expressing Desire and Willingness

Querer signifies a desire or willingness to perform an action. It can be translated as “want” or “would like” in English. Here are some examples:

Deber: Expressing Obligation and Probability
