Poseidon
Poseidon's name is usually parsed as "husband" or "lord" of "Da" (earth), though the second element remains genuinely disputed, and the name is already attested centuries before Homer.

Meaning
The most widely cited breakdown of Poseidon's name splits it into two elements: posis, "husband" or "lord" (from the Proto-Indo-European root *pótis, the same root that gives Latin "potent" and "despot" its second half), and a second element da, read as a Doric dialect form of gē, "earth." Put together, the name would mean something like "lord of Da" or "husband of Earth" - a striking reading, since it would make Poseidon etymologically the consort of an earth-goddess, pairing conceptually with Demeter, whose name is built on a similar earth element. The difficulty is that this second element, da, is not securely attested as an independent word meaning "earth" outside of these two theonyms. The classicist Walter Burkert judged the element "hopelessly ambiguous" and considered a confident "husband of Earth" reading impossible to prove on the existing evidence - a caution that has not stopped the theory from being repeated as though settled in many popular sources. It remains the leading scholarly hypothesis, but a hypothesis rather than a demonstrated fact. What is not in dispute is the name's antiquity. Poseidon appears already in Mycenaean Linear B tablets, written as po-se-da-o or po-se-da-wo-ne, corresponding to a Mycenaean Greek Poseidaōn or Poseidawonos. This places the name in continuous use for roughly half a millennium before the Iliad and Odyssey were composed, making Poseidon one of the best-attested Bronze Age god-names in the entire Greek record - striking given that in the Mycenaean period he appears to have outranked Zeus in some cult contexts, a status the etymology's "earth" element may or may not explain.
What does the name Poseidon actually mean?
The leading theory reads it as "lord" or "husband" (posis, from Proto-Indo-European *pótis) "of Da" (earth), roughly "lord of the earth." It is the most widely repeated etymology, but the meaning of the second element, da, is genuinely disputed among scholars rather than firmly settled.
Why do scholars doubt the "earth" etymology for Poseidon?
Because the element da is not clearly attested elsewhere as an ordinary Greek word for "earth" independent of these god-names. Walter Burkert called it "hopelessly ambiguous" and said a confident "husband of Earth" reading could not be proven, even though it remains the most commonly cited theory in handbooks and reference works.
How old is the name Poseidon?
It is one of the oldest securely attested Greek divine names, appearing in Mycenaean Linear B tablets as po-se-da-o and po-se-da-wo-ne roughly five hundred years before Homer. This shows Poseidon was already a major worshipped figure in the Bronze Age, well before the Olympian mythology familiar from later Greek literature took shape.
