Before entering fully into establishing the meaning of the term receiver , we have to proceed to determine its etymological origin. Specifically, we can affirm that it derives from the Latin word for “receiver” as it is the result of the sum of the following elements:
-The prefix “re-”, which indicates repetition.
-The verb “capere”, which is synonymous with “capture”.
-The suffix “-tor”, which is used to indicate the person who performs an action.
