I'm developing a system in which users can 'link' separate items by using a 'Link' button. In the database, this 'link' is called a 'relation'. I'm inclined to change the text of the button to 'Relate' instead of 'Link' because it seems more correct. However, I fear users might be confused due to popular usage of the term 'relation'.
For example, you often see a list with 'Related terms' popping up on websites. When you look closely, most of the time this is a list of terms that might have something to do with the current term you have selected, but don't have an actual relation to it. I would rather call it 'Similar terms'.
Might 'link' therefore be a better choice after all? Or is 'relation' much more correct?
