المعنى الاصطلاحي :

Deriving a word or more from another word, with a correlation between them in pronunciation and meaning.

الشرح المختصر :

"Ishtiqaaq" (derivation) is to form a word or more from another word such that the original word implies the derived word and is indicative of it; e.g. the word "Ruboobiyyah" (Lordship) is derived from the noun "Rabb" (Lord). So the noun "Rabb" implies "Ruboobiyyah" and more. The same applies to all of Allah’s beautiful Names, such as Al-`Aleem, Ar-Raheem, and others. There are three kinds of "ishtiqaaq": 1. "Sagheer" (Small): where a word is derived from another word by changing its form while retaining a correlation in meaning and the radicals (root consonants) of the original word in the same order; e.g. "daraba" (beat) is derived from "darb" (beating). 2. "Kabeer" (Big): where there is a correlation between the two words in meaning and the radicals are retained but not in the same order; e.g. "hamida" (praised) is derived from "mad-h" (praise). 3. "Akbar" (Bigger): where there is a correlation between the two words in meaning and they share only some of of the radicals and their order; e.g. "khariqa" (tore apart) and "kharaba" (ruined). 4. "Kubbaar" (Biggest) or "naht" (coining): where a new word is coined from letters taken from two words or more; e.g. "Basmala" means 'said Bismillah' (In the name of Allah).
