ΩΚΕΑΝΌΣ

The Greek word ωκεανός [okeanos], meaning "ocean," has long been considered of unknown origin, lacking a clear etymology within the Greek language. In contrast, the Georgian word for "ocean," უქიანე [ukiane], exhibits a transparent morphological structure: u- + <root> + -e, a common Kartvelian formation for abstract nouns. This structure provides a promising avenue for uncovering the etymology of okeanos through a Kartvelian lens.

The root kian in უქიანე offers several potential interpretations, each shedding light on the term’s possible origins:

1. The root may be linked to the name of the Georgian village Kianeti, meaning "the land of the kiani." While the meaning of kiani in this context remains unclear, the toponym suggests a historical or cultural association that warrants further exploration.
2. Kian could be an adjective derived from the root ki or ka, though the precise meaning of this root is similarly uncertain, leaving this interpretation speculative.
3. According to linguist Georgy Klimov, the root kian signifies "wavy," "fluctuating," or "rippled." In this framework, ukiane, with the negative prefix u-, becomes an abstract noun meaning "absence of fluctuations" or "absence of ripples"—essentially "a state of rest." This interpretation aligns with the historical naming of the Pacific Ocean, which early European explorers described as calm, naming it "Pacific" (from Latin pacificus, "peaceful") due to its tranquil appearance.
4. The Kartvelian word უყი [uki] means both "soil" and "depth." The adjective ukiani, derived from this root, can be translated as "muddy" but may also relate to the secondary meaning of "depth," thus interpreting ukiane as "deep." This aligns with the conceptual association of oceans with profound depths.
5. The most compelling interpretation, however, traces ukiane to the Megrelian word kiani (ქიანა), which, in Otari Kajaia’s dictionary, means "land" or "world" (ქვეყანა). With the negative prefix u-, ukiane can be flawlessly interpreted as "absence of land"—a strikingly apt description for the vast, landless expanse of the ocean.

Among these possibilities, the Megrelian-derived meaning "absence of land" offers the most coherent and contextually appropriate etymology for ukiane, which likely influenced the Greek ωκεανός. The phonetic similarity between ukiane and okeanos, combined with the lack of a native Greek etymology, suggests that the term was borrowed from a Kartvelian language, with the Greek form adapting the Kartvelian root to its phonological system.

This Kartvelian etymology not only provides a clear origin for ωκεανός but also underscores the deep linguistic interactions between Kartvelian-speaking peoples and the ancient Greeks, challenging the assumption that such fundamental terms in Greek are of unknown or Indo-European origin.
