Word Family
The original core of this root was a sense of:
death, exhaustion, collapsing
But this soon shifted toward the idea of “lack of something”.
In English to need , and also in the Slavic branch, the sense shifted further toward the idea of need.
In German, it is also about lack, but it kept more of a sense of emergency.
