A nymph (nýmphē, nímfi; nýmphɛː, ˈniɱfi), sometimes spelled nymphe, in ancient Greek folklore is a minor female nature deity. Different from other Greek goddesses, nymphs are generally regarded as personifications of nature, are typically tied to a specific place or landform, and are usually depicted as maidens. They were immortal like other goddesses, except for the Hamadryads, whose lives were bound to a specific tree.
They are often divided into various broad subgroups, such as the Meliae (ash tree nymphs), the Dryads (oak tree nymphs), the Naiads (freshwater nymphs), the Nereids (sea nymphs), and the Oreads (mountain nymphs).
Nymphs are often featured in classic works of art, literature, mythology, and fiction. Since the Middle Ages, nymphs have been sometimes popularly associated or even confused with fairies.
The Greek word nýmphē has the primary meaning of "young woman; bride, young wife" but is not usually associated with deities in particular. Yet the etymology of the noun nýmphē remains uncertain. The Doric and Aeolic (Homeric) form is nýmphā (νύμφα).
Modern usage more often applies to young women, contrasting with parthenos (παρθένος) "a virgin (of any age)", and generically as kore (κόρη < κόρϝα) "maiden, girl". The term is sometimes used by women to address each other and remains the regular Modern Greek term for "bride".
Nymphs were sometimes beloved by many and dwelt in specific areas related to the natural environment: e.g. mountainous regions; forests; springs. Other nymphs were part of the retinue of a god (such as Dionysus, Hermes, or Pan) or of a goddess (generally the huntress Artemis).
The Greek nymphs were also spirits invariably bound to places, not unlike the Latin genius loci, and sometimes this produced complicated myths like the cult of Arethusa to Sicily. In some of the works of the Greek-educated Latin poets, the nymphs gradually absorbed into their ranks the indigenous Italian divinities of springs and streams (Juturna, Egeria, Carmentis, Fontus) while the Lymphae (originally Lumpae), Italian water goddesses, owing to the accidental similarity of their names, could be identified with the Greek Nymphae.
