IPA: //eɪˈsɪmɛtrɪkli//
KK: /ˌeɪsɪˈmɛtrɪkli/
In a way that is not the same on both sides or not equal in size, shape, or arrangement.
The two sides of the sculpture were asymmetrically designed to create a unique visual effect.
Asymmetrically → It is formed from "a-" (meaning not) and "symmetria" (from Greek, meaning together or proportion). The word describes something that does not have a balanced or proportionate arrangement.
Think of 'not' ('a-') having 'balance' or 'proportion' ('symmetria') — that's why asymmetrically means lacking balance.
