Vergleichbarkeit vs Vergleich
comparison / settlement
'der Vergleich' and 'die Vergleichbarkeit' belong to the same topic area, but they do not mean the same thing. 'Vergleich' is the action or text in which you compare things with each other. 'Vergleichbarkeit' refers to the question of whether you can meaningfully compare those things at all. Learners may confuse the words because both come from the verb 'vergleichen' (to compare). Remember: first you need comparability, then a comparison can make sense.
Vergleichbarkeit
