E.g. Russell: two readings:
(1) George IV did not know whether Scott was the author of Waverley.
Description/Logical Form/Russell/Hintikka: "The Author of Waverley": (ix) A (x)
Primary: the description has the following force:

(2) (Ex)[A(x)&(y)A(y) > y = x) & George IV knew that (Scott = x).
((s) notation: the quantifier is here always a normal existence quantifier, mirrored E).
That is, the quantifier has maximum range in the primary description.
More likely, however, is the second reading:

(3) ~ George IV knew that (Ex)[A(x) & (y) > y = x & (Scott = x)].
((s) narrow range)
Range/HintikkaVsRussell: he did not know that there is a third possibility for the range of a quantifier ((s) "medium range"> Kripke,> wolf).

(4) ~ (Ex) [A(x) & (y)(A (y)> y = x) & George IV knew that (Scott = x)].
