Suppose a sentence contains mushtari and it is not yet clear whether it refers to a purchaser or the planet. There is lexical multiplicity without a settled intended sense.
If other indications make the purchaser sense stronger, the interpretation rests on reasoned preference. If the speaker explicitly explains, “Here I mean the purchaser,” the speaker’s clarification directly fixes the intended sense.
The word form remains the same across these cases, but the route by which its meaning becomes known differs. That distinction is particularly consequential in interpreting legal texts.
