oxia

Etymology
From the, an elliptical use for — ἡ (hē, the nominative feminine singular form of ὁ, ho, “the”, the ) + ὀξεῖᾰ (okseia, the nominative feminine singular form of ὀξῠ́ς, oksus, “sharp”, of sound “shrill”, of tones “high-pitched”) + προσῳδῐ́ᾱ (prosōdiā, “variation in pitch of the speaking voice”, “pronunciation of a syllable on a certain pitch”, “a mark [i.e., a ] indicating normally unwritten differences of pronunciation, viz. vowel quantity, breathing, and pitch”).

Noun

 * 1)  An  pitch-marking : ⟨ &#8189; ⟩; written atop vowels, it denotes high pitch on short vowels, and rising pitch on long vowels and diphthongs.

Usage notes

 * In a diphthong, the oxia is written atop the second of the two vowels.
 * The oxia is virtually identical in form to the Latin-script : ⟨ &#180; ⟩.
 * The Modern Greek stress-marking diacritic, the : ⟨ &#900; ⟩, was originally designed as a vertical line, thereby constituting a compromise of forms between the Ancient Greek oxia and ; nevertheless, the oxia and tonos have identical appearance in all but the most scrupulous typesetting.
