The word unforcible is derived from the prefix un- meaning not or lack of, and the adjective forcible which comes from the verb force. The term force traces its origins to the Latin word fortis, meaning strong or powerful. Over time, forcible came to mean capable of being forced or compelled. By adding the prefix un- to forcible, the word unforcible takes on the meaning of not capable of being forced or compelled.
