IPA: /əˈmɔːrfəsli/
KK: /əˈmɔr fəslē/
In a way that lacks a clear shape or form; without a definite structure.
The clouds floated amorphously across the sky, changing shape constantly.
Amorphously → It is formed from "a-" (meaning without) and "morphe" (from Greek, meaning form or shape) and the suffix "-ous" (meaning full of). The word describes something that is without a definite form or shape.
Think of 'without' ('a-') and 'form' ('morphe') to remember that 'amorphously' means lacking a definite shape.
