IPA: /ʌnˈpɒlɪʃt/
KK: /ʌnˈpɑlɪʃt/
Not refined or sophisticated; lacking in smoothness or finish.
The artist's style was raw and unpolished, giving it a unique charm.
Unpolished → It is formed from "un-" (meaning not) and "polished" (from Latin "polire", meaning to make smooth or shiny). The word "unpolished" means not made smooth or shiny, indicating a lack of refinement or finish.
Think of 'not' ('un-') being added to 'made smooth' ('polished') — that's why unpolished means something that is not smooth or refined.
