U+03CC "ό" Greek Small Letter Omicron with Tonos Unicode Character
Unicode Version 17.0
ό
U+03CC "ό" Greek Small Letter Omicron with Tonos is a glyph used in the modern Greek writing system to represent the omicron vowel (ο) when it carries a stress mark, known as the tonos. This diacritical marker indicates that the syllable containing this letter should be pronounced with emphasis, distinguishing it from the unstressed version of the same letter. While historically derived from the polytonic system of ancient Greek, the tonos is now the sole accent mark in monotonic Greek orthography, making this character essential for accurate spelling and pronunciation in contemporary Greek texts, such as in words like "λόγος" (logos/logos).
