Forms

ἕλος (hélos) n (genitive ἕλεος or ἕλους); third declension[1] Mycenaean e-re-e, Cypriot syllabic e-le-i (dative).[2]

Etymology

It is inherited from Proto-Hellenic *hélos, inherited from Proto-Indo-European *sélos (“marsh”), an inherited word identical with Sanskrit सरस् (sáras, “pond”).[3][1] The adjective ἕλειος (héleios) matches a Sanskrit adjective in the same way.[3] The DGE takes the root to be the one found in river names, as in the Sanskrit river name Sarasvatī.[2]

It is not related to Latin silva (“forest”) or to ὕλη (hū́lē).[3][4]

Earliest recorded meaning

The Mycenaean tablets have a form e-re-e, according to the DGE.[2] In Homer it is a wet meadow by a river where horses graze, as in the Iliad (4.483 and 20.221).[5][6]

Semantic evolution

In the Odyssey it already means marshy ground with reeds, and this is the usual sense in Herodotus, Thucydides, Xenophon and Plato: a marsh or swamp.[5][7] Theophrastus speaks of plants that grow in marshes, and in Apollonius of Rhodes it is a shady backwater.[2][5] In the Septuagint it is used of the marshy bank of the Jordan.[2]

Medieval Greek kept the word.[8] It survives as Modern Greek έλος (élos), a learned word for a marsh, with derivatives such as Modern Greek ελώδης (elódis).[9][4]
