The funny thing about English — funny in an infuriating way, for non-native speakers — is its spelling irregularities.
A friend in Poland once offered me “duff nuts.” Logical enough: -ough is often pronounced “uff,” as in “enough.”
K asked me the other day if I knew what cat soup was. I suddenly became very protective of our own cat, wondering what kind of Third-World recipe she had in mind. Turned out, we have cat soup in our fridge; it’s just spelled a little differently.
