Onomastics (or onomatology in older texts) is the study of proper names, including their etymology, history, and use.
An alethonym ('true name') or an orthonym ('real name') is the proper name of the object in question, the object of onomastic study. Scholars studying onomastics are called onomasticians.
Ancient Macedonian was the language or dialect spoken by the ancient Macedonians during the 1st millennium BC. It was either an ancient Greek dialect—part of Northwest Greek or Aeolic Greek—or a distinct Indo-European language, related to Greek and part of the Hellenic branch. Spoken originally in the kingdom of Macedon, it gradually fell out of use during the 4th century BC, marginalized by the use of Attic Greek by the Macedonian aristocracy, the Ancient Greek dialect that became the basis of Koine Greek, the lingua franca of the Hellenistic period. It became extinct during either the Hellenistic or Roman imperial period, and was entirely replaced by Koine Greek.
While the bulk of surviving public and private inscriptions found in ancient Macedonia were written in Attic Greek (and later in Koine Greek), fragmentary documentation of a vernacular local Macedonian variety comes from onomastic evidence, ancient glossaries, and recent epigraphic discoveries in the Greek region of Macedonia, such as the curse tablets from Pella and Pydna.
The Caspians (Persian: کاسپیها, Kaspyn; Greek: Κάσπιοι, Káspioi; Aramaic: ܟܣܦܝ, kspy; Old Armenian: Կասպք, Kaspk’; Latin: Caspi, Caspiani) were an people of antiquity who dwelt along the southwestern shores of the Caspian Sea, in the region known as Caspiane. Caspian is the English version of the Greek ethnonym Kaspioi, mentioned twice by Herodotus among the Achaemenid satrapies of Darius the Great and applied by Strabo. The name is not attested in Old Iranian.
The Caspians have generally been regarded as a pre-Indo-European people. They have been identified by Ernst Herzfeld with the Kassites, who spoke a language not identified with any other known language group and whose origins have long been the subject of debate. Onomastic evidence bearing on this point has been discovered in Aramaic papyri from Egypt published by P. Grelot, in which several of the Caspian names that are mentioned—and identified under the gentilic כספי kaspai—are, in part, etymologically Iranian. The Caspians of the Egyptian papyri are therefore generally considered as either an Iranian people or strongly under Iranian cultural influence.
Toponymy, toponymics, or toponomastics is the study of toponyms (names of places, also known as place names and geographical names), including their origins, meanings, usage, and types. Toponym is the general term for the name of any geographical feature, and the full scope of the term also includes names of all cosmographical features.
In a more specific sense, the term toponymy refers to an inventory of toponyms, while the discipline researching such names is referred to as toponymics or toponomastics. Toponymy is a branch of onomastics, the study of names of all kinds. A person who studies toponymy is called toponymist.
A theonym (from Greek theos (Θεός), 'god', attached to onoma (ὄνομα), 'name') is a proper name of a deity.
Theonymy, the study of divine proper names, is a branch of onomastics, the study of the etymology, history, and use of proper names. Theonymy helps develop an understanding of the function and societal views of particular gods and may help understand the origins of a society's language.
Trees hold a particular role in Germanic paganism and Germanic mythology, both as individuals (sacred trees) and in groups (sacred groves). The central role of trees in Germanic religion is noted in the earliest written reports about the Germanic peoples, with the Roman historian Tacitus stating that Germanic cult practices took place exclusively in groves rather than temples. Scholars consider that reverence for and rites performed at individual trees are derived from the mythological role of the world tree, Yggdrasil; onomastic and some historical evidence also connects individual deities to both groves and individual trees. After Christianisation, trees continue to play a significant role in the folk beliefs of the Germanic peoples.
