Mu'jam Masaadir al-Af'aal ath-Thalaathiyyah

As you know most of the words in Arabic are formed on a root of three letters which then allows to decline quite a range of names, verbs or adjectives according to letters and accents that are added.

This dictionary are cataloging all verbs with a root of 3 letters in alphabetical order and gives its meaning, if it is transitive or intransitive if (muta'addī / Lazim), its shape to Moudari 'and finally its Masdar (names of action).

A very useful book, therefore, with the majority harakats.
