The term "sense and reference" is a common phrase used in philosophy and linguistics to describe the two aspects of meaning in language. The spelling of "sense" is /sɛns/, with the "e" pronounced as in "red," and the "s" pronounced as a voiceless consonant at the end of the word. The spelling of "reference" is /ˈrɛf(ə)rəns/, with the stress placed on the first syllable and the "e" pronounced as in "red" again. The "f" and "s" are both pronounced as voiceless fricatives, with the final "s" pronounced as a voiced consonant.
Sense and reference are two fundamental concepts in the field of semantics and philosophy of language, introduced by the German philosopher and logician, Gottlob Frege.
Sense refers to the meaning or understanding that a word or expression carries with it. It can be understood as the mental concept or idea associated with a particular word or phrase in the mind of a speaker or hearer. The sense of a word is related to its cognitive content and how it is mentally grasped.
On the other hand, reference is the actual object or entity in the world that a word points to or denotes. It is the external or extralinguistic reality that is being referred to by a specific linguistic expression. The reference of a word is determined by the actual objects or concepts it represents in the external world.
The distinction between sense and reference is crucial because the same reference can be associated with different senses. For example, the phrase "the morning star" and "the evening star" both refer to the same celestial body, Venus. However, they have different senses as they are used to describe the same object at different times of the day.
Overall, sense and reference play a significant role in understanding how words and expressions carry meaning and refer to external objects or concepts. They form the basis for analyzing the semantics of language and the relationship between language and the world it represents.
