# Grelling's paradox

<*logic*>
If an adjective truly describes itself, call it "autological",
otherwise
call it "heterological". For example, "polysyllabic" and "English"
are
autological, while "monosyllabic" and "pulchritudinous" are
heterological.
Is "heterological" heterological? If it is, then it isn't; if it
isn't,
then
it is. Grelling's paradox cannot be expressed in first-order
predicate
logic, and is difficult to prevent in higher-order predicate
logics.
