modális

Modális, also known as modal verbs, are a class of verbs in English that express various concepts such as possibility, obligation, ability, or permission. They are used to modify the main verb in a sentence, providing additional information about the action or state described by the main verb. Modal verbs do not have a past tense or a plural form, and they are always followed by a base form of the main verb (infinitive without "to").

The most common modal verbs in English include can, could, may, might, must, shall, should, will, and would. Each of these verbs has its own specific uses and nuances. For example, "can" is used to express ability, while "may" is used to express permission or possibility. "Must" indicates a strong obligation or necessity, whereas "should" suggests a weaker obligation or advice.

Modal verbs are essential in English grammar as they help to convey the speaker's attitude, intention, or certainty about the action or state described by the main verb. They are often used in conditional sentences, requests, and to express future possibilities. For instance, "If I had known, I would have helped" uses "would" to express a hypothetical situation, while "You can leave now" uses "can" to express permission.

In summary, modális, or modal verbs, are a crucial component of English grammar that provide additional information about the main verb in a sentence. They help to express concepts such as possibility, obligation, ability, or permission, and are essential for conveying the speaker's attitude and intention.
