Toponymy is the scientific study of place names (
toponyms), their origins, meanings, use and
typology. The first part of the word is derived from the
Greek tópos (t?p??),
place; followed by
ónoma (???µa), meaning
name. It is itself a branch of
onomastics, the study of names of all kinds. To understand the value of toponyms, visualize each toponym (or geographical name) as the title of a story revealing some aspect of a region's cultural or natural heritage.
Toponyms are not just words on maps and signs, but vital communication tools that reflect patterns of settlement, exploration, migration, and heritage that may otherwise be overlooked by residents, visitors, and future generations. A toponym is a named point of reference in both the physical and cultural landscape on the Earth's surface. This includes natural features, such as streams (whose names are studied as hydronyms) and artificial ones (such as cities). Natural features are no more geographical than man-made features or administrative units because all such features have names that are in essence artificially applied. Toponyms are typically conservative and give insight into the buried human history of a region. For example Moses I. Finley observed, "it is significant that the bulk of the towns and districts in Greece in historical times retained their pre-Greek names";[1] viewed with archaeological remains, the conclusion is that speakers of proto-Greek infiltrated the region by degrees, rather than in a massive invasion, and that they found already in place a comparatively highly-developed culture.
In ethnology, a toponym is a name derived from a place or a region. In anatomy, a toponym is a name of a region of the body, as distinguished from the name of an organ. In biology, a toponym is a binomial name of a plant.
A toponymist is one who studies toponymy. According to the Oxford English Dictionary, the word toponymy first appears in English in 1876; since then, toponym has come to replace "place-name" in professional discourse among toponymists. It can be argued that the first toponymists were the storytellers and poets who explained the origin of certain place names in order to elucidate their tales; sometimes place-names served as the basis for the etiological legends themselves. The process of folk etymology usually took over, whereby a false meaning was extracted from a name based on its structure or sounds. Thus, the toponym of Hellespont was explained by Greek poets as being named after Helle, daughter of Athamas, who drowned here as she crossed it with her brother Phrixus on a flying golden ram. The name, however, most likely is derived from an older language, such as Pelasgian, which was unknown to those who explained its origin. George R. Stewart theorized, in his book Names on the Globe, that Hellespont originally meant something like "narrow Pontus" or "entrance to Pontus," "Pontus" being an ancient name for the region around the Black Sea, and by extension, for the sea itself.[2]
