bhI;trArthAnAm bhaya-hetuH

भीॱत्रार्थानां भयॱहेतुः ONPANINI 14025

When the meaning is fear or protection, the reason for fear is called /apAdAna.

An /apAdAna takes fifth ending by apAdAnep....

So the word caurebhyaH चौरेभ्यः is called /apAdAna here:

caurebhyo bibheti चौरेभ्यो बिभेति "is afraid from thieves"
caurebhyas trayate चौरेभ्यस्त्रयते "protects from thieves"

Why do we say arthAnAm अर्थानाम्?

It is not just derivatives of bhI भी and tra त्र, but of all roots meaning fear or protection —

caurebhyo rakSati चौरेभ्यो रक्षति "protects from thieves"
