Siddhaṃ script
(also '), also known in its later evolved form as Siddhamātṛkā, is a medieval Brahmic abugida, derived from the Gupta script and ancestral to the Nāgarī, Assamese, Bengali, Tirhuta, Odia and Nepalese scripts.
The word means "accomplished" or "perfected" in Sanskrit. The script received its name from the practice of writing ', or ' (may there be perfection), at the head of documents. Other names for the script include "bonji" () lit. "Brahma's characters" and "Sanskrit script" and lit. "Siddhaṃ script".

 is an abugida rather than an alphabet, as each character indicates a syllable, including a consonant and (possibly) a vowel. If the vowel sound is not explicitly indicated, the short 'a' is assumed. Diacritic marks are used to indicate other vowels, as well as the anusvara and visarga. A virama can be used to indicate that the consonant letter stands alone with no vowel, which sometimes happens at the end of Sanskrit words.
