IPA: /ˈpleɪs.ləs.li/
KK: /ˈpleɪs.ləs.li/
In a manner that lacks a specific location or position.
The artist created a world that felt placelessly, as if it existed outside of time and space.
Placelessly → It is formed from "place" (from Old French *place*, meaning a specific location or position) and "-less" (meaning without) and "-ly" (meaning in a manner). The word "placelessly" means in a manner that is without a specific place or location.
Think of being 'without' ('-less') a 'place' — that's why placelessly means lacking a specific location.
