<span class="mw-page-title-main">Assamese alphabet</span> Writing system of the Assamese language

The Assamese alphabet is a writing system of the Assamese language and is a part of the Bengali-Assamese script. This script was also used in Assam and nearby regions for Sanskrit as well as other languages such as Bodo, Khasi, Mising, Jaintia etc. It evolved from Kamarupi script. The current form of the script has seen continuous development from the 5th-century Umachal/Nagajari-Khanikargaon rock inscriptions written in an eastern variety of the Gupta script, adopting significant traits from the Siddhaṃ script in the 7th century. By the 17th century three styles of Assamese alphabets could be identified that converged to the standard script following typesetting required for printing. The present standard is identical to the Bengali alphabet except for two letters, ৰ (ro) and ৱ (vo); and the letter ক্ষ (khya) has evolved into an individual consonant by itself with its own phonetic quality whereas in the Bengali alphabet it is a conjunct of two letters.

In the Japanese language, the gojūon (五十音, Japanese pronunciation:[ɡo(d)ʑɯꜜːoɴ], lit. "fifty sounds") is a traditional system ordering kana characters by their component phonemes, roughly analogous to alphabetical order.

As depicted at the right using hiragana characters, the sequence begins with あ (a), い (i), う (u), え (e), お (o), then continues with か (ka), き (ki), く (ku), け (ke), こ (ko), and so on and so forth for a total of ten rows of five columns.
