The state or quality of being ordinary or usual, not special or unique.
The commonplaceness of the scenery made the journey feel less exciting.
Commonplaceness → It is formed from "common" (from Old French *comun*, meaning shared by all) and "place" (from Latin *locus*, meaning location or position) combined with the suffix "-ness" (meaning the state or quality of). The word "commonplaceness" refers to the state of being ordinary or unremarkable, shared by many.
Think of something that is 'shared by all' ('common') in a certain 'location' ('place') — that's why commonplaceness means the quality of being ordinary.
