HOW REFERENCE OCCURS: WORDS, SENSES AND OBJECTS A WORD W REFERS to an OBJECT O if W is conventionally associated with SENSE S and S is a SENSE of O. The word REFERS to whatever the SENSE determines. Therefore, the SENSE mediates between the sign (word) and what the sign (WORD) refers to. SENSES AND WORDS Words are connected with SENSES in a way that is different from how OBJECTS are connected with SENSES. Words are associated with senses purely by convention. For example, the fact that the word “star” refers to a star (mediated by its sense) is a matter of convention. The WORD REFERS to whatever the SENSE determines. Each linguistic expression has both a SENSE and a REFERENCE. Different words or phrases can have the same SENSE.
