# Often Confused Terms

There are many terms that are very similar and can many times be used interchangeably. This isn't wrong per se, a slight difference may be insignificant in certain contexts and the list here may also serve as a list of synonyms to those who already know the differences. However it's important to stress it's important to know at least some of the differences for the sake of the cases where they matter. The following list tries to document some of the often confused/similar terms.
