  Most languages that use alphabets based on the Arabic alphabet use the same base shapes. Most additional letters in languages that use alphabets based on the Arabic alphabet are built by adding (or removing) diacritics to existing Arabic letters. Some stylistic variants in Arabic have distinct meanings in other languages. For example, variant forms of kāf ك ک ڪ are used in some languages and sometimes have specific usages. In Urdu and some neighbouring languages, the letter Hā has diverged into two forms ھ dō-čašmī hē and ہ ہـ ـہـ ـہ gōl hē, while a variant form of ي yā referred to as baṛī yē ے is used at the end of some words.
