U+1FBD "᾽" Greek Koronis Unicode Character

U+1FBD "᾽" Greek Koronis is a diacritical mark used in ancient Greek polytonic orthography, primarily functioning as a sign of crasis, which indicates the contraction of a vowel at the end of one word with a vowel at the beginning of the next word. It resembles a smooth breathing mark but appears above the vowel of the resulting contracted form, distinguishing it from an apostrophe that marks elision. Historically, the koronis helped readers identify where lexical blending occurred, such as in phrases like "κἀγώ" (from "καὶ ἐγώ"). In modern typography, it is encoded separately from the similar-looking apostrophe or smooth breathing to preserve its specific scribal tradition.
