Unpalatable → It is formed from "un-" (meaning not) and "palatable" (from Latin "palatum", meaning the roof of the mouth or taste). The word "unpalatable" means not pleasant to taste or not agreeable to the palate.
Think of 'not' ('un-') being added to 'taste' ('palatable') — that's why unpalatable means something that is not pleasant to taste.
