IPA: //ʌnˈlʌvli//

Something that is not attractive or pleasant in appearance or character.

Unlovely → It is formed from "un-" (meaning not) and "lovely" (from Old English "luflic", meaning full of love or affection). The word "unlovely" means not full of love or affection, often referring to something unattractive or unpleasant.
Think of 'not' ('un-') being added to 'full of love' ('lovely') — that's why unlovely means something that is not attractive or pleasant.
