Understanding the Phrase “Be Able To” in English
The phrase “be able to” functions as a modal-like expression used to indicate capability or possibility. Unlike the modal verb “can,” which is limited to present and past forms (“can” and “could”), “be able to” can be used in all tenses, making it a crucial structure for expressing ability accurately in different time contexts.
The Structure of “Be Able To”
The phrase consists of three parts:
- Be: The appropriate form of the verb “to be” according to the subject and tense (am, is, are, was, were, will be, etc.)
- Able: An adjective meaning capable or competent
- To + base verb: The infinitive form of the main verb indicating the action
Example: She is able to speak three languages fluently.
