líffræðilegs

Líffræðilegs is a declined form of the Icelandic adjective líffræðilegur, meaning biological. It is used in contexts related to biology and the life sciences to describe attributes, processes, or nature that pertain to living organisms.

Etymology and formation: The word líffræðilegur is formed from líffræði, meaning biology, combined with the adjective suffix -legr, which yields the meaning “biological.” Líffræðilegs represents a specific inflected form of that adjective, used in grammatical contexts that require a genitive singular form.

Grammatical notes and usage: In Icelandic, adjectives decline for gender, number, and case. Líffræðilegs is typically the genitive singular form of líffræðilegur, and it appears before a masculine or neuter noun in genitive, or in fixed phrases where a genitive construction is required. A common usage is with the phrase líffræðilegs eðlis, meaning “of biological nature.” The corresponding go-to neuter or feminine forms are líffræðilegt and líffræðileg, respectively, in other cases and numbers.

Context and scope: The term is primarily found in scientific, academic, and technical Icelandic writing. It helps distinguish biological aspects from non-biological ones and is part of the standard vocabulary for describing topics in biology, medicine, ecology, and related fields.
