neljakordse

Neljakordse is an Estonian adjective meaning fourfold or quadruple. It describes a quantity, size, or rate that is four times as large as a reference value. The term is used across mathematics, statistics, economics, science, and everyday language to express a multiplier of four. For example, neljakordne kasv refers to growth that is four times as large as a comparison, and neljakordse suurusega denotes a size that is fourfold.

The word is formed from the numeral neli (four) and the word kord (times, fold). It declines like other Estonian adjectives, with neljakordne as the base form in nominative singular and neljakordse as the genitive singular form, among other inflection patterns.

In usage, neljakordne provides a precise multiplier: something is neljakordne if it exactly equals four times another quantity. In formal writing, it is common to use neljakordne to convey exact multipliers, whereas in everyday speech people might say neli korda suurem (“four times bigger”). The term appears in scientific reports, statistical analyses, and news coverage when proportional changes or comparative sizes are described.

Notes: neljakordse should not be confused with approximate phrasing; it conveys an explicit fourfold multiplier. Related expressions include kaks korda (twice) and kolm korda (three times).
