I wanted to make sure to cover words we don't hear often as well as ones we do. Today I want to bring the word Cantankerous into your awareness. This word is probably of latin origin and means difficult or cumbersome.
Looking into the etymology of this fun word it sounds like it probably was first used to describe someone who is ill-tempered or a troublemaker. According to etymonline.com it's 'from Anglo-French contec "discord, strife,"'. Today it's used to describe anything that is difficult as often as it is used to describe a person.
