I just started to dig into suffixes and prefixes. But I couldn't understand how do they exactly change the meaning of the word that they are appended.
For example re- means again, retake means take again. Inter- means between, but interact means acting in a way that you have an effect on something. Interact has no connection with between. Why is that?
re-
not-re
. Not all words starting with what appears to be a suffix are suffixed.
