Suorakulmaisessa

Suorakulmaisessa is the inessive singular form of the Finnish adjective suorakulmainen, meaning rectangular. It is used to describe something that is located inside a rectangle or refers to a state described as rectangular form. The adjective derives from suorakulmio (rectangle) plus the suffix -inen.

Grammar and usage: Finnish adjectives decline for case, number, and other grammatical categories. The inessive case, indicating location inside something, is marked by -ssa or -ssä. Therefore suorakulmainen becomes suorakulmaisessa when modifying a noun in the inessive: for example, suorakulmaisessa muodossa (“in rectangular form”) or suorakulmaisessa koordinaatistossa (“in the rectangular coordinate system”).

Common contexts: In mathematics and geometry, the phrase is frequent. In complex-number theory, suorakulmaisessa muodossa describes the rectangular form a + bi. In architecture or design, it may describe layouts or spaces described as rectangular, such as suorakulmaisessa tilassa.

Examples: “Kompleksiluku z voidaan esittää suorakulmaisessa muodossa a + bi.” “Piste (x, y) voidaan esittää suorakulmaisessa koordinaatistossa.” These usages illustrate how the form functions in technical Finnish to denote a rectangular representation or context.
