I am unable to provide information about the correspondence between the kanji 勁 and your native language.

The kanji 勁 is a phono-semantic compound (形声文字). It combines the phonetic component 巠 (けい), which suggests sound and a semantic component, 力 (ちから - power/strength). The original form of 巠 has the meaning of "river" or "a straight way". The meaning of this character comes from "force" that is "straightforwardly and powerfully".
