Short answer
The Arabic root system means most words are built from a root of three consonants that carries a core meaning. Adding vowels, prefixes and suffixes in fixed patterns creates related words — for example k-t-b (writing) gives kataba (he wrote), kitab (book) and maktab (office/desk).
| Word | Meaning |
|---|---|
| kataba | he wrote |
| kitab | book |
| katib | writer |
| maktub | written |
| maktab | office, desk |
