kahekordne

Kahekordne is an Estonian adjective meaning twofold or doubled. It describes something that is twice as large, numerous, or complex, or something consisting of two parts. In use, it typically precedes the noun it modifies and agrees with it in number and case, as in kahekordne arv (a twofold number) or kahekordne summa (a double amount).

Origin and form: The word is built from the numeral kaks (two) in a form related to kahe, combined with kord (occurrence, time) to convey the idea of “two times.” As an attributive adjective, kahekordne follows standard Estonian adjective inflection rules and can take different endings to match the noun it describes in various cases and numbers.

Usage in mathematics and science: In mathematical and scientific contexts, kahekordne is used to indicate a doubling operation or a construct with two dimensions. Common phrases include kahekordne integraal (double integral) and kahekordne kasv (twofold growth). It also appears in descriptions of twofold properties or effects, such as kahekordne mõju or kahekordne tähelepanu.

Language note: Kahekordne is a standard Estonian term and is widely understood in formal and everyday language. In more colloquial speech, speakers may opt for explicit phrases like kaks korda suurem ("two times larger") to express the same idea, depending on nuance and register.
