Arabic is built from three-letter roots poured into a handful of moulds. Learn six roots and four moulds and you can read two dozen words — and it keeps scaling.
Build a word
Pick a root and a mould, and a real word appears. Swap either one to feel the system work.
1 · pick a root
2 · pick a mould
The moulds
Each mould carries a meaning, whatever root you pour into it. The فعل in each template just marks the three root slots.

This is Arabic’s superpower: meaning lives in the root, shape lives in the mould. Once م-ك-ت-ب clicks, you can guess مكتبة, كاتب and مكتوب are all about writing.
