You can define a function as the action for which a person or thing is specially fitted or used or for which a thing exists or any of a group of related actions contributing to a larger action. Does that help you understand it better? It doesn't for me but thats mostly because design doesn't work by dictionary definitions and when dealing with functions on your designs there are different and varied ways in which they are considered and these may be different between design engineers. What we discuss here is just one of those approaches.
