3-letter root (lesson 2)

As we spoke earlier about 3-letter root rule in most Arabic words, briefly I would like to remind you with basic word types.
In Arabic language we have word types:

verb = فِعْل  &   noun = اسْم  &  particle= حرف

***The 3-letter root doesn't necessarily exist in particles ....
