An act of joining  or the state of being joined

This word was encountered in the first paragraph of hills like white elephants.

“The American and the girl with him sat at a table in the shade, outside the building. It was very hot and the express from Barcelona would come in forty minutes. It stopped at this junction for two minutes and went on to Madrid.”

I actually always  thought that this word had a deeper/more complex meaning and that the word was just a description of an action.But that’s just not the case here.
