IPA: /ˌʌnɪˈmædʒɪnd/
KK: /ʌnɪˈmædʒɪnd/
Describing something that has not been thought of or envisioned before.
The artist created an unimagined world filled with vibrant colors and strange creatures.
Unimagined → It is formed from "un-" (meaning not) and "imagined" (from Latin "imaginari", meaning to form a mental image). The word "unimagined" means not formed in the mind or not conceived.
Think of 'not' ('un-') and 'forming a mental image' ('imagined') — this helps you remember that 'unimagined' refers to something that has not been conceived in thought.
