Could someone pls tell me the difference of between these three words?
Feasible/Possible/Potential
I don't want to rpeat every meaning in the dictionary, so perhaps it would be better if you tried to write a few sentences with these words. Then I can tell you if they sound OK, and whether the words can be interchanged in them.
These are the definitions of the words that I think you are wanting. There are many others.
Possible means that it can happen. Feasible means not only that it is possible but it makes sense taking into account financial and other considerations. Potential can mean 'has the prerequisite talents that with training can make a skilled individual'.
