indexical expression मीनिंग इन हिंदी

Ernie Lepore suggests that this approach treats " definite descriptions as harboring hidden indexical expressions, so that whatever descriptive meaning alone leaves unfinished its context of use can complete ".
Later linguists have amended this definition, because in order to determine the truth value of a sentence, enough context must be known to be able to disambiguate ambiguous expressions, assign references to variables, interpret indexical expressions, fill in ellipses, and so on.
