An inflection used in Arabic for the comparative and the superlative Wikipedia Disambiguation

In Semitic languages, the “adjective degree of superiority.” In some languages such as Arabic, the concepts of comparative and superlative degree of an adjective are merged into a single form, the elative. How this form is understood or translated depends upon context and definiteness. In the absence of comparison, the elative conveys the notion of “greatest”, “supreme.”. Wiktionary
