An epithet (Greek - επιθετον and Latin - epitheton; literally meaning 'imposed') is a descriptive word or phrase. It has various shades of meaning when applied to real or fictitious people, divinities, objects and biological nomenclature. It also means a derogatory word or phrase used to insult someone. See List of political epithets.
Some epithets are known by the Latin term epitheton necessarium because they are required to distinguish the bearers, e.g. as an alternative to ordinals after a prince's name—say Richard the Lionheart, or Charles the Fat alongside Charles the Bald. Still the same epithet can be used repeatedly, in different spheres of life and/or joined to different names, say Alexander the Great as well as Suleiman the Great.
Other epithets can easily be omitted without serious risk of confusion, and are therefore known (again in Latin) as Epitheton ornans; thus the classical Roman author Virgil systematically called the armsbearer of Aeneas, his main hero, fidus Achates, the epithet being fidus, which means faithful or loyal.
In contemporary usage, epithet is also used to refer to an abusive or defamatory phrase, such as a racial epithet.
There are also specific types of epithets, such as the kenning, also known as periapsis, which appears in works such as Beowulf. An example of a kenning would be the term whale-road, meaning "sea".
Some epithets were applied to several deities of a same pantheon, rather accidentally if they had a common characteristic, or deliberately emphasizing their blood- or other ties; thus in pagan Rome, several divinities (including demi-gods, heroes) were given the epitheton Comes as companion of another (usually major) divinity. An epithet can even be meant for collective use, e.g. in Latin pilleati 'the felt hat-wearers' for the brothers Castor and Pollux.
Alternatively the epithet may identify a particular and localized aspect of the god, sometimes already ancient during the classical epochs of Greece and/or Rome, such as a reference to the mythological place of birth or other genesis. It often appears to refer simply to a main center of veneration and/or some cultic tradition there, but often this is actually the result of an intercultural equation of a divinity with another, usually older, that is generally considered its pendant; thus most Roman gods and goddesses, especially the twelve main ones, had traditional counterparts in Greek, Etruscan and most other Mediterranean pantheons, e.g. Jupiter as father of the Olympian Gods with Zeus, but in specific cult places there may even be a different equation, based on one specific aspect of the divinity. Thus the Greek word Trismegistos "thrice grand" was first used as a Greek name for the Egyptian god of science and invention, Thot, and later as an epitheton for the Greek Hermes and finally the fully equated Roman Mercurius (Mercury; both were also messenger of the gods).
Similar practices still exist in Christianity (Catholic and Orthodox, not Protestant) in the veneration of Christ and, mainly, of the saints, e.g. Our Lady of Lourdes, - of Mercy etc.
Indeed while these differ from official titles as they don't express any legal status, epitheta have been awarded and adopted (though the official procedure may provide for the formal decision to be issued by another institution, such as a legislative assembly) by statesmen in power for fairly formal use, not unsimilar in purpose to various sinecures, knighthoods or peerage-type titles in post-feudal societies: they confer prestige without any legal authority, so essentially a matter of image or even propaganda, aimed at a domestic and/or foreign target audience. Examples of such epithets are the various traditions of victory titles (see there) awarded to meritous generals and rulers since Antiquity, and the epithets awarded to entire units, e.g. such adjectives as 'Fidelis' 'loyal' to various Roman legions.
Arisaema candidissimum - here, candidissimum is the epithet.
Passiflora edulis var. flavicarpa - both edulis and flavicarpa are epithets.
