IPA: /ˈfɔːmləs/
KK: /ˈfɔrm.ləs/
Not having a specific shape or structure; lacking form or organization.
The artist created a formless sculpture that challenged traditional ideas of art.
Formless → It is formed from "form" (from Latin "forma", meaning shape or appearance) and "-less" (meaning without). The word "formless" describes something that lacks a definite shape or structure.
Think of something that is 'without' ('-less') a 'shape' ('forma') — that's why formless means lacking a clear form.
