التقاء ساكنين

In Arabic grammar, التقاء ساكنين (Iltika’ al-Sakinayn) refers to the “meeting of two consonants” without an intervening vowel. This situation is generally avoided in Arabic phonology because it can make pronunciation difficult. When two consonants meet, various strategies are used to resolve the issue, such as inserting a vowel or dropping one of the consonants.
