IPA: //ʌnˈrɪəl//
KK: /ʌnˈriəl/
Something that is not real or does not exist; it can also refer to something so amazing that it seems unbelievable.
The special effects in that movie were so unreal that I felt like I was in a dream.
Unreal → It is formed from "un-" (meaning not) and "real" (from Latin "realis", meaning actual or true). The word "unreal" means not real or lacking in reality.
Think of 'not' ('un-') being added to 'real' — this helps you remember that 'unreal' means something that is not real.
