I would like to draw the attention of students, who are aiming to improve their Spoken English skills, towards a very common mistake that most people do while speaking English. The usage of Can & Able together in a statement/sentence.
Few examples:
1. I can able to do this.
2. I can't able to do this.
3. Can you able to do this?
This is completely wrong. We are not supposed to use both Can & Able together in a statement/sentence as Can & Able mean the same. Two words of the same meaning should never be used in a single statement/sentence.
The correct way of saying this is:
1. I can do this (or) I am able to do this.
2. I can't do this (or) I am unable to do this.
3. Can you do this? (or) Are you able to do this?
Hope this helps.
Thank you!
