Vänstersidiga

Vänstersidiga is a Swedish adjective meaning left-sided, used to describe something that is located on or affects the left side of the body or of a structure. The term is formed from vänster (left) and sida (side) with the common adjectival ending, and appears in various inflected forms depending on gender, number, and definiteness. In practice, the neuter singular form is vänstersidigt, while the attributive plural form is typically vänstersidiga and is used before plural nouns.

The word is most common in medical and anatomical contexts, where it denotes left-sided localization or involvement. Examples include vänstersidiga symtom (left-sided symptoms), vänstersidiga förändringar (left-sided changes), or vänstersidig kärl-/neurologisk påverkan (left-sided vascular or neurological involvement). It is often contrasted with högersidiga, meaning right-sided, and with bilateral when both sides are affected.

Usage notes:

- The term is usually placed before the noun it describes (e.g., vänstersidiga smärtor).

- The neuter singular form vänstersidigt is used with neuter singular nouns (often in generic or adverbial constructions).

- In medical records and radiology reports, vänstersidiga is common to indicate left-sided findings or symptoms.
