The Sinhala script (Sinhala: සිංහල අක්ෂර මාලාව, romanized: Siṁhala Akṣara Mālāva), also known as Sinhalese script, is a writing system used by the Sinhalese people and most Sri Lankans in Sri Lanka and elsewhere to write the Sinhala language as well as the liturgical languages Pali and Sanskrit. The Sinhalese Akṣara Mālāva, one of the Brahmic scripts, is a descendant of the Ancient Indian Brahmi script. It is also related to the Grantha script.
