Reference

Reference is the problem of determining which objects are referred to by phrases.

A pole supports a weight at one end.

Determiners:

• Indefinite: a

  
        Make a new object.
  

• Definite: the, one, etc.

  
        Find an existing object;
  else, find something closely related
        to an existing object;
  else, make a new one.
  

In reading the above sentence, we create a new pole object and a new weight object, but look for an existing end: one end of the existing pole.
