kraadide

Kraadide is the genitive plural form of the Estonian noun kraad, a basic unit of measurement used for both angles and temperatures, as well as in figurative or quantitative scales. In standard usage, phrases such as “kraadide arv” (number of degrees) or “kraadide väärtus” (value in degrees) appear in scientific, technical, and everyday contexts to specify a quantity measured in degrees.

Etymology and grammar: The word kraad is a native Estonian term with cognates in several Germanic languages, and it is used in Estonian to denote degree as a unit of measurement. The form kraadide marks possession or association in the genitive plural, enabling phrases like “kraadide erinevus” (difference of degrees) or “kraadide suurus” (size of degrees). The genitive plural is common in technical writing to link the unit to a corresponding quantity.

Usage and examples: Common expressions include “90 kraadi” (90 degrees) for angles and “temperatuur on 25 kraadi” (the temperature is 25 degrees) in meteorology or daily speech. The term appears in mathematical, physical, and engineering contexts to describe rotations, inclinations, or temperature values. While “aste” is another Estonian word for degree in some contexts, kraad remains the standard unit in many scientific and technical phrases.
