neonatalis

Neonatalis is a Latin-derived adjective used in scientific terminology to indicate a relation to the neonate, that is, a newborn organism or human infant. The form comes from neonat- meaning newborn, combined with the suffix -alis, which is used in Latin and in scientific nomenclature to form adjectives.

In medical and biological texts, neonatalis appears primarily within Latin phrases or in taxonomic descriptions where Latin grammar governs gender agreement. In modern English medical writing, the noun neonatal and the adjective neonatal are far more common, while neonatalis is typically encountered in Latinized passages, historical works, or as a component of species epithets in taxonomic names that aim to express an association with early life stages.

The use of -alis adjectives in taxonomy allows naming conventions to convey characteristics or associations without implying a separate diagnostic category. Therefore, neonatalis does not by itself denote a clinical condition; rather, it functions as a descriptive label within the appropriate Latin or taxonomic context. In everyday clinical practice, discussions of newborns will use terms such as neonatal, newborn, or neonatal period rather than neonatalis.
