hygieinos

Hygieinos is the masculine form of the ancient Greek adjective ὑγιεινός (hygieinos), meaning healthy, wholesome, or hygienic. The feminine form is ὑγιεινή and the neuter form ὑγιεινόν. In classical Greek, ὑγιεινός described things believed to promote health, such as regimens, foods, climates, medicines, and habits considered conducive to well-being. The term is the etymological foundation of modern words relating to health and cleanliness, giving rise to English hygiene and its derivatives, including hygienic, hygiene, and related terms, via Latin and French transmissions from the Greek root.

As a proper name, Hygieinos is not widely attested in surviving Greek texts; when it appears, it is typically the masculine form of a descriptive epithet rather than a common given name. In some later sources and transliterations, the form may be encountered as a personal name or as part of a compound name, but such occurrences are rare and not central to its primary linguistic function.

In summary, hygieinos denotes healthful or hygienic qualities in ancient Greek usage and provides the linguistic root for contemporary concepts and terms related to health, cleanliness, and disease prevention.
