Derived from the adjective `dauerhaft` (durable) plus the noun-forming suffix `-igkeit` (equivalent to '-ness' or '-ity'). `dauerhaft` is composed of `Dauer` (duration) and `-haft` (having the quality of).
Memory Tips
Connect `Dauer` to the English word 'duration'. The `-haftigkeit` part signifies a quality. So, it's the 'quality of long duration'.
