Deontology

Deontology is a noun that refers to the study of obligation. Our word of the day’s origin comes mainly from Greek. The Greek prefix D-E-O-N-T means ‘being needed,’ while the suffix L-O-G-Y — also from the Greeks — denotes study. Here’s an example of deontology in use: I wasn’t sure how to approach the situation, but after a careful look at the deontology of it, I understood my true obligation. Sometimes taking a good at things and weighing out your moral duty can be helpful.
