Lete

There is no mythological origin for a supernatural 'Lete' in the provided material. The documented origins concern names and lexical formation: in Basque onomastics, the surname Lete derives from a place named Lete in Iza, Navarre, and branches of the family are recorded in Gipuzkoa and Benabarra; the ancient city called Lete is attested in Mygdonia of Macedon; in Toki Pona the lexical item 'lete' was created within that constructed-language vocabulary to mean 'cold'; and the string 'Lete' has been adopted in modern contexts as an esolang name, as an ICAO airport code (LETE), and as the proper name of an exoplanet (HD 102195 b).

As a lexical and toponymic form, 'Lete' has no physical appearance as a being. The only pictorial depiction in the consulted sources is the Toki Pona glyph for lete, described as depicting a high-pressure system with cold air descending from a cloud; otherwise appearances recorded under 'Lete' are human individuals bearing the surname (e.g., Xabier Lete, Elene Lete), cartographic/placename markers (ancient city, Nepalese village), and non-physical artifacts (programming language, ICAO code, exoplanet name).

No supernatural powers or behaviors are ascribed to 'Lete' in the sources. Functional behaviors associated with non-mythical uses include: the esolang Lete enforces an append-only editing model (code cannot be deleted once entered) as a language/IDE constraint; the Toki Pona lexical item 'lete' functions semantically to denote 'cold' in sentences and texts.
