Finding the root
Arabic dictionaries are organised by ROOT, not by spelling. To look up مَكْتُوب, strip the add-ons: ma- prefix, -ūb vowel pattern — the skeleton is ك-ت-ب. Look up k-t-b and you find "write"; the pattern mafʿūl means "thing that is X-ed", so maktūb = "written / a letter". Strip, look up root, apply pattern: three steps that unlock any word you meet.
Verb forms change meaning
Arabic grows meanings by stretching the same root through numbered patterns. Form I عَلِمَ ʿalima "he knew"; Form II عَلَّمَ ʿallama (doubled middle) "he taught" — making someone know; Form IV أَعْلَمَ aʿlama "he informed". You have already met this with darasa/darrasa. Spotting the form tells you HOW the root’s core idea is being used — knowledge you can apply immediately in the morphology explorer on any Quran word.
A real passage
Read: العِلْمُ نُورٌ، وَالجَهْلُ ظَلامٌ. طَلَبُ العِلْمِ فَرِيضةٌ عَلى كُلِّ مُسْلِمٍ. — "Knowledge is light, and ignorance is darkness. Seeking knowledge is a duty upon every Muslim." Work root by root: ع-ل-م (know), ن-و-ر (light), ج-ه-ل (be ignorant), ظ-ل-م (darkness), ط-ل-ب (seek), ف-ر-ض (obligate). Every root here appears across the Quran — you now read with the same toolkit scholars use.
You see كتب with no marks. It could be كَتَبَ (he wrote), كُتِبَ (it was written), or كُتُب (books). Which one? Look at the sentence. If it follows a subject noun and is followed by an object, it is a verb. If it comes after عِنْدي or a preposition, it is the plural noun. Grammar decides, not vocabulary — which is why grammar becomes indispensable exactly here.
