The 3-Letter Root System

Nearly every Arabic word traces back to a 3-letter root (جِذْر). From a single root, Arabic derives verbs, nouns, adjectives, participles and verbal nouns — all sharing a common core meaning.

How does it work?

Take the root ك ت ب (k-t-b). Its core meaning is writing. By slotting these 3 letters into different patterns (called awzān), Arabic produces:

  • كَتَبَ (kataba) — he wrote (verb)
  • كِتَاب (kitāb) — book (noun)
  • كَاتِب (kātib) — writer (active participle)
  • مَكْتُوب (maktūb) — written (passive participle)

Master the root system and you can decode unfamiliar words by recognising the root + pattern combination.
