fyrkantiga

Fyrkantiga is a Swedish adjective meaning square-shaped or four-cornered. It is formed from the noun fyrkant, meaning a four-cornered figure, with the suffix -ig. The neuter singular form is fyrkantigt, while the plural form is fyrkantiga, used for plural nouns in both indefinite and definite contexts. It is used to describe objects that have roughly square form or four distinct corners, such as en fyrkantig låda (a square-shaped box) or fyrkantiga fält i en karta (four-cornered or square-ish fields on a map).

In everyday language, fyrkantig describes shapes that appear four-cornered and is not necessarily precise about equal sides or right angles. In mathematical or geometric contexts, kvadratisk is typically used to denote a true square or square-shaped properties, with fyrkantig serving a broader sense that includes various quadrilaterals like rectangles as well.

Etymology and grammar notes: fyrkantiga derives from fyrkant (“four-cornered figure”) plus the suffix -ig. The word shows standard Swedish adjective inflection, with fyrkantigt for neuter singular and fyrkantiga for plural forms. As with many adjectives in Swedish, fyrkantiga agrees with the noun it modifies in number and definiteness.
