Singular Terms/Intentionality/Referencing Expressions/Millikan: Singular terms may even have an even more complicated intentionality than whole sentences!
1. Appears a singular term within a sentence. That is, this is the normal condition for its eigenfunction.
2. Within the context of the sentence, it is to correspond to an object (map an object).
