Undang-Undang Melaka, also known as Hukum Kanun Melaka, Undang-Undang Darat Melaka and Risalah Hukum Kanun, was the legal code of Melaka Sultanate (1400–1511). It contains significant provisions that reaffirmed the primacy of Malay customary law or adat, while at the same time accommodating and assimilating Islamic principles. The legal code is believed originally compiled during the reign of Muhammad Shah (1424–1444), before it was continuously expanded and improved by the succeeding sultans. The Melaka system of justice as enshrined in the Undang-Undang Melaka was the first digest of laws, compiled in the Malay world. It became a legal resource for other major regional sultanates like Johor, Perak, Brunei, Pattani and Aceh, and has been regarded as the most important of Malay legal digests.

Jawi is a writing system used for writing several languages of Southeast Asia, such as Acehnese, Malay, Mëranaw, Minangkabau, Tausūg, and Ternate. Jawi is based on the Arabic script, consisting of all of the original 31 Arabic letters, and six additional letters constructed to fit the phonemes native to Malay, and an additional phoneme used in foreign loanwords, but not found in Classical Arabic, which are ca, nga, pa, ga, va, and nya.
