Language
This is a good one; we all use some form of language everyday, but how do you define it? Technically, we can say that language is a formal system of communication which involves the combination of words and/or symbols, whether written or spoken, as well as some rules that govern them. It is not even necessary for another organism to comprehend the language, for it to actually be a language, just that it meets the above description.
