Gaf (Persian: گاف; gāf), is the name of different Perso-Arabic letters, all representing /ɡ/. They are all derived from the letter kāf, with additional diacritics, such as dots and lines. In name and shape, it is a variant of kaf. It is also one of the five letters the Persian alphabet added to the Arabic alphabet (the others being ژ, پ, and چ in addition to the obsolete ڤ).

Jawi was developed during the advent of Islam in Maritime Southeast Asia, supplanting the earlier Brahmic scripts used during Hindu-Buddhist era. The oldest evidence of Jawi writing can be found on the 14th century Terengganu Inscription Stone, a text in Classical Malay that contains a mixture of Malay, Sanskrit and Arabic vocabularies. However, the script may have used as early as the 9th century, when Peureulak Sultanate has been established by the son of a Persian preacher. There are two competing theories on the origins of the Jawi alphabet. Popular theory suggests that the system was developed and derived directly from the Arabic script, while scholars like R. O. Windstedt suggest it was developed with the influence of the Perso-Arabic alphabet.
