This question already has an answer here:
- ことができる versus V~える form 4 answers
A couple of days ago I tried to express "I can ..." where "..." was some some verb or verb phrase.
I used the ～て form of the ... verb followed by 出来ます but was told instead to change the form of the ... verb from ～います to ～えます.
So now it seems to me that both 出来る and ～えます can have similar functions. What is the real difference and how can I know which to use when?
