  • 10th-century Byzantine: /oˈmi.xli/[1]

Forms

ὀμῐ́χλη (omíkhlē) f (genitive ὀμῐ́χλης); first declension[1]

Etymology

It is inherited from Proto-Hellenic *omíkʰlā, inherited from Proto-Indo-European *h₃migʰleh₂ (“fog”), with the suffix of νεφέλη (nephélē).[1][2][3] It is identical with the Balto-Slavic word for fog, Lithuanian miglà and Old Church Slavonic мъгла (mŭgla).[2][3][4] Beside this l-formation stand a root noun with zero grade, Sanskrit मिह् (míh-, “mist”), and a full-grade o-stem, Sanskrit मेघ (meghá-, “cloud”); Old Armenian մէգ (mēg, “mist, fog”) probably belongs here too.[2][3][1] Frisk explains the initial ὀ- as a prothetic vowel, while Beekes, who reconstructs a laryngeal Proto-Indo-European *h₃-, sees in Armenian the regular loss of that laryngeal before m.[3][2]

Some scholars connect it with ὀμείχω (omeíkhō, “to urinate”), but that verb has a palatal /ǵʰ/, which Indo-Iranian excludes for this word, and Frisk and Beekes keep them apart.[2][3][5] The Attic form is ὁμίχλη (homíkhlē), with a rough breathing that the ancient grammarians condemned.[1][5][6]

Ancient writers explained it as a “mist of the eyes”, from ὄμμα (ómma) and ἀχλύς (akhlús), or from ὁμοῦ (homoû), “together”, because the clouds whirl in one place.[7]

Earliest recorded meaning

Homer has it only in the Iliad, for a mist that the south wind spreads over the mountain tops, for Thetis rising from the sea like a mist, and for a cloud of dust.[6][8][9]

Semantic evolution

In Aeschylus' Prometheus a mist full of tears falls on the eyes, and Aristophanes personifies Mist and uses it figuratively for what hides wrongdoing.[6][9] Xenophon and Polybius use it of fog on a march or a battlefield, and Aristotle defines it as thinner than a cloud.[6][10] Later poets used it for the gloom of night, and a comic poet for the steam of cooking.[6]

Medieval Greek kept the word, and Modern Greek has ομίχλη (omíchli), fog.[11][12][7]
