Welcome to another easy English lesson! Today, we are learning about a multi-tool phrase: (be) able to.
Think of “(be) able to” as the cousin of the word Can. They have the exact same superpower: they both talk about things you know how to do or have the power to do.
But “(be) able to” has a secret magic trick. While the word “can” is stuck only talking about the present, (be) able to can travel through time! It lets you talk about your skills in the past, the present, and the future.
đ ī¸ 1. The Time Machine: How to Build the Sentences
This phrase uses the verb to be (am/is/are/was/were/will be). To build a sentence, you change the “be” part to match your time zone and the person speaking.
Change “be” to am, is, or are.
- I am able to…
- He / She / It is able to…
- You / We / They are able to…
- Example: “She is able to speak three languages.” (Meaning: She can do it right now).
Change “be” to was or were.
- I / He / She / It was able to…
- You / We / They were able to…
- Example: “After trying for an hour, I was able to fix my computer.” (Meaning: I managed to do it).
Add will in front of the word be. This one is easy because “will be” never changes!
- Everyone + will be able to…
- Example: “With enough practice, you will be able to play the piano.” (Meaning: You will have the skill later).
â 2. Saying “No” (The Negative Way)
To say you do not have the power or skill to do something, simply add the word not to your “to be” verb.
- Present: “I am not able to come to the party tonight.” (Shortcut: I can’t come).
- Past: “They were not able to catch their flight.” (Shortcut: They weren’t able to).
- Future: “He will not be able to join the meeting tomorrow.” (Shortcut: He won’t be able to).
đ¯ 3. Why do we need “(be) able to” if we have “Can”?
This is a question many students ask! There are two main reasons:
You can never say “I will can help you tomorrow.” That is a major English rule error! When you want to talk about future skills or possibilities, you must use will be able to.
- “Next year, I will be able to drive a car.”
When something was very difficult in the past, but you worked hard and successfully completed it one time, using was/were able to sounds much more natural to native speakers than could.
- “The mountain was steep, but the hikers were able to reach the top.”

đŽ 5. A Creative Story: The Locked Video Game Level
Let’s see how this looks in real life. Two friends, Leo and Ken, are playing a difficult video game together.
Leo: “Oh man, this volcano level is impossible! I am not able to jump over the hot lava blocks right now.” (Present problem → am not able to jump)
Ken: “Let me try. Wow, look at that! I was able to cross the bridge on my first try!” (Past success → was able to cross)
Leo: “Lucky! I tried five times yesterday and I wasn’t able to do it even once.” (Past failure → wasn’t able to do)
Ken: “Don’t worry. If you watch my movements and practice for another ten minutes, you will be able to beat this boss monster too.” (Future skill → will be able to beat)
Leo: “Awesome. Once we finish this level, will we be able to save our game progress?” (Asking about future possibility → will we be able to save)
Ken: “Yes! The game autosaves, so we will be able to turn off the console safely whenever we want.” (Future guarantee → will be able to turn off).
