IPA: /ˈaɪsləs/
KK: /ˈaɪsləs/
Not containing or made with ice.
The drink was served iceless, making it less cold than usual.
The word 'iceless' is formed from 'ice' (from Old English 'is', meaning frozen water) and '-less' (meaning without). Therefore, 'iceless' means without ice or lacking ice.
Think of 'ice' as frozen water and '-less' meaning without — so 'iceless' describes something that is without ice.
