rechteckigem

Rechteckig is a German adjective meaning rectangular. It is used to describe objects, shapes, or layouts that have the shape of a rectangle. The word derives from Rechteck (rectangle) plus the adjectival suffix -ig.

Rechteckigem is a declined form of rechteckig. In German, adjectives show different endings depending on grammar, including whether a determiner is present and what case the noun has. Rechteckigem is the dative singular form used for masculine or neuter nouns when the adjective stands without a determiner (strong declension). For example, in phrases like In rechteckigem Raum stehen mehrere Tische or Mit rechteckigem Grundriss wird der Raum geplant, the adjective carries the ending -em, resulting in rechteckigem.

In everyday usage, speakers more often include a determiner or use a different case form. Examples with determiners include ein rechteckiger Tisch (nominative masculine), das rechteckige Fenster (nominative neuter), or dem rechteckigen Tisch (dative masculine with definite article). When describing a rectangular shape without a determiner, the strong form rechteckigem appears in the appropriate case, as in In rechteckigem Raum.

Related terms include Rechteck, the geometric figure; rechteckig, the base form of the adjective; and the broader topic of German adjective declension (weak, mixed, and strong endings).
