 GRAMMAR 2 WILL BE ABLE TO: MODALS MAY AND MIGHT

Will (or won´t) be able to + base form: future ability 

The form Be able to is used in English to talk about skills and also to talk about having the resources to do something. This expression has two possible translations in Spanish: BE CAPABLE OF and POWER. Examples:

I will be able to cook delicious dishes after I finish the cooking course. / I will be able to cook delicious dishes once I finish the cooking course.

I'd like to be able to run as fast as you do. / I would like to be able to run as fast as you.

May: Indicates possibility. It can also be used to give or ask permission, give suggestions in formal contexts.

Examples:

He may be eating.

May I call you?

You may sit here.

Might: Also indicates possibility but less probable than May. It is not used to ask permission. It is used as the past tense of May in the case of Indirect Speech or Indirect Reported Speech.

Examples:

Examples:
