Can you infer the definition of the word "unbearable," given that the prefix of the word is "un-"?

The word Unbearable is made up of three morphemes: a prefix (un), a root word (bear) and a suffix (able). Morphemes are the smallest unit of the meaning of a word but that can not stand on its own.

So, in order to infer the definition of the word, we must find out the meaning of each morpheme: un means not, bear means to support, carry the weight of or to endure and able means capable of. Unbearable, then, refers to something that can not be endured.

"Un" means "not", which means the word "unbearable" means "not bearable".
