IPA: //ʌnˈlaɪkəbl//
KK: /ʌnˈlaɪkəbl/
Not pleasant or agreeable; difficult to like.
His rude behavior made him seem unlikeable to his classmates.
Unlikeable → It is formed from "un-" (meaning not) and "likeable" (from "like" meaning to find agreeable or enjoyable, combined with "-able" meaning capable of being). The word "unlikeable" means not capable of being liked or not enjoyable.
Think of 'not' ('un-') being added to 'likeable', which means something that cannot be found agreeable or enjoyable.
