If you're talking about C++ keywords, this is just something that you'll have to learn. For example, if you don't know what the if() statement is, then not every if() word on this app should be highlighted, it's just something you have to go back and learn.

If it's just general words, you coulds always look up these words to find their meaning, or if it's a nationality issue, maybe you don't understand English so well, then consider looking up some guides on the web for your language, garuntee they'll be one.

Good luck :)
