Relating to ownership or the rights of a property owner.
The company's proprietorial attitude made it difficult for employees to express their ideas freely.
Proprietorial → It is formed from "proprietor" (from Latin "proprietarius", meaning owner) and the suffix "-ial" (meaning relating to). The word "proprietorial" means relating to an owner or ownership.
Think of 'proprietor' as someone who 'owns' something, and '-ial' means relating to. So, 'proprietorial' helps you remember that it relates to ownership.
