Joining Group - Nun

Nun is the joining group assigned to the Arabic letter nun, which appears in forms like ن in isolated and initial positions, and ـن in medial and final contexts. This group defines how the letter connects to adjacent characters in scripts that use cursive joining behavior, such as Arabic and Syriac. Specifically, nun belongs to the category of letters that join on both sides, meaning it connects to the preceding and following characters within a word, but its exact joining behavior can vary depending on the script and the specific character variant. In Arabic, the nun group typically behaves as a dual-joining letter, while in Syriac, it may exhibit different connection rules based on the version of the script. The group designation helps ensure correct text shaping and rendering, particularly for complex text layouts where letters change shape depending on their position in a word.
