I'd like to know how can I learn about prefixes and suffixes in the internet. Do you know any sites which I can consult??
I'm here again... thanks for the sites indication!
but I have many doubts...
if both UN and IN is used to indicates NOT/OPPOSITE how can I know when I use IN or UN?
How can I know if the word has a prefix?
for e.g. Is "RE" a prefix of reduction ??
