Step-by-step explanation:
Commonplace refers to something that is ordinary, commonly seen or experienced, or widely accepted. It can also mean a shared or communal resource that can be accessed or used by anyone within a group. For example, the oceans are a commons for fishing, and if anyone can emit air pollution, then the atmosphere is a commons.
Commonplace can also describe a tendency to do or believe something because many other people do or believe the same thing. It can be a reflection of the majority opinion on certain issues.
Everyday tasks that are done regularly, such as brushing teeth or washing dishes, can also be referred to as commonplace.
