Katakana Sa

It represents the sound sa; the surrounding word supplies the meaning. Katakana and hiragana are Japanese scripts whose characters represent sounds. Replacing サ with hiragana さ changes the written form, not the sound.

Katakana does not automatically signal emphasis. It is conventional spelling in loanwords and foreign names; in a word normally written in hiragana, it can make the wording stand out.

Where does サ come from?

サ is traditionally traced to part of the Chinese character 散. Early katakana appears in early 9th-century manuscripts with notes on Chinese texts. Buddhist scholars shortened Chinese characters used for their sounds into compact marks that indicated Japanese readings beside the text.

サ is traditionally traced to the first three strokes of 散; hiragana さ developed through cursive writing of 左. These are different written sources for the same sound. Katakana forms moved toward standardization by the 12th century.

Katakana's role grew beyond reading notes. In modern Japanese, it also writes technical terms and sound effects, as well as loanwords, foreign names, and words marked for emphasis.

How do I type サ?

With Japanese romaji input active, type sa and choose Katakana. Romaji input lets you enter Japanese using Latin letters. If the result is さ, the input has produced hiragana; convert it to katakana rather than changing the letters you type.
