LessonsTen Semantic Functions of Form X (Istifʿāl): Seeking, Suitability, Finding, Judging, Transformation, Adoption, Abbreviation, Response, Equivalence and Independent UseQuiz

The other two comparisons are:
اِسْتَكْبَرَ وَتَكَبَّرَ
Translation: He acted arrogantly or regarded himself as great.
اِسْتَعْصَمَ وَاعْتَصَمَ
Translation: He sought/held firmly to protection.
The first compares Form X with Form V, and the second with Form VIII. These pairs show a possible overlap in the meaning of derived patterns. Such lexical equivalence is example-specific; it does not make their morphological patterns identical or prove that every derivative of the same root is synonymous.
