PS - Roots can be modified by consonants too, and not just vowels.
If we say that C = a consonant of the root (in Arabic 90% of words are formed from three consonants, KTB, QWL, SJD, SLM, etc.)
KTB = things to do with writing
SJD = things to do with bowing down
SLM = things to do with peace
Inserting short 'a' vowels between each root consonant, gives you the perfect (or past tense) verb in the 3rd person singular masculine, or 'he'. So, KaTaBa (he wrote), SaJaDa (he bowed down), etc.
But adding a ma/mu to the start gives the place/person who does the thing. So maKTaB (place of writing = office), maSJiD (place of bowing down = mosque), and muSLiM (person who is peaceful = Muslim).
There are many, many more patterns, but you get the idea. All very logical.
