kahekordsed

Kahekordsed is Estonian an adjective meaning twofold or double. It describes something that is twice as large, twice as much, or that occurs in two parts or copies. The form kahekordsed is used with plural nouns, for example kahekordsed väärtused (twofold values) or kahekordsed kogused (twofold quantities). In everyday language, kahekordne is often used in a more formal or technical sense, while topelt may be used in colloquial speech as a synonym in some contexts.

Usage and meaning

In mathematics and science, kahekordne commonly denotes multiplication by two. A kahekordne arv is a number obtained by doubling another number, and kahekordne suurus refers to a quantity twice as large. In statistics or data presentation, kahekordsed can describe increases or comparisons expressed as “twofold.” The term can also apply to physical objects or plans that come in two copies or are designed to be used in pairs, for example kahekordsed koopiad (two copies) or kahekordsed süsteemid (two-part systems).

Etymology and morphology

The word is formed from kaks (two) and kord (time, instance) with an Estonian adjectival ending, yielding kahekordne in singular and kahekordsed in plural. It is related to other terms for doubling, such as topelt, though kahekordne is the more precise, often formal, mathematical usage.
