SIR: Why do so many use "whelps" when they are referring to the red "welts" raised by insect stings or bites? I was pretty sure dogs had "whelps," but I looked it up again to be positive and I was right. Could this error be indigenous to south Indiana? - Mildred B.

ANSWER: My goodness, no. People all over claim to have found whelps on their skin. I don't know why, but let's just be thankful they're wrong. Otherwise, the world would be plumb full of puppy-dogs.SIR: I have been engaged in a fierce discussion over a word that may or may not exist: "unsufferable." Webster's does not list it, and Oxford calls it "archaic" and "dialect."

I have been through university stacks looking for a solution to what has become a bitter discussion between two very hard-headed people. Please resolve this issue. Of course, I know "insufferable" is legal. - John S.

ANSWER: And so is "unsufferable," and you'll find it in plenty of dictionaries.

SIR: Recently you objected to the expression, "It was so fun," though you said you couldn't find a rule against it. That's easy. "Fun is a noun, and nouns cannot be modified by adverbs. "So" is an adverb. - Numerous writers.

ANSWER: That's true as far as it goes, and perhaps I should have said so and left it at that. But unfortunately, the noun "fun" is also becoming an adjective before our eyes and is being recognized as one - a fun person, a fun gift, a fun group. And adjectives can be modified by adverbs. So how do we head it off in that case?

"My newspaper said many people `wretched' at something they saw on television. This is an example of such wretched English that it almost made me retch."
