You know the conical end of a ballpoint pen that holds the ball inside the end of the conical shaped end of the ballpoint? Is there a name for the conical end? I am thinking it has a name, but I never learned what the name was. Does it also come with several names? If it's the case, what are they?
From Merriam-Websters's definition of ballpoint pen:
: a pen having as the writing point a small rotating metal ball that inks itself by contact with an inner magazine
Note that the definition uses the phrase writing point, which makes sense. So, really, the end of a ballpoint pen is its point.
