A current favourite phrase at work is "quarter-wit" (for the times when half-wit seems to be a compliment)

A fairly limited category perhaps, but are there any other valid "re-sized" words?

Along the same line, my father used to say, "If you said that [name] was a wit, you'd be half right."

and, crossthreading to quavers, you might encounter the hemisemidemiwit -- who might be indistinguishable (without aid of a witometer) from a wittol.

Wittol: wwftd. I could not find out if the word was derived from name of character in Congreve play, or if Congreve named the character from a pre-existing word.

I have noticed that lately the Spam I receive has changed from porn to physiologic enhancement products for both sexes. Upsizing, not downsizing.

we should check OED, but W3 traces it from ME wetewold as in cokewold (cuckold).

Goatboy asks an interesting question and could we please get back to it ? Welcome Goatboy...Don't give up, we tend to go off on tangents but eventually an answer emerges, even if it takes a year and a day. Right Max?
I hope for elucidation on downsized words as I haven't a witter!

Dear wow: the reason goatboy's question did not get answered is that none of us know any such words. To tease you a bit,I double dare you to post some.

Double dare.

What do y'all take this phrase to mean?

Double dare: since my second childhood is close at hand, I am reverting to childish challenges.

in truth or dare, it's when you get two dares instead and you get to choose the lesser of the evils.

Well bill, there is alwasy the expression that "Their IQ is equal to the shoe size" and the new rejoinder," and i think they lie about what size shoes they wear... "

it all modern day evolution.. engineers go out and build idiot proof machines, and god( or the what ever force you want to name) goes out and provides the world with a better class of idiot.. so to keep the engineers employed...

>are there any other valid "re-sized" words?

wow, I had two(2) problems with this question: what is meant by a "re-sized" word, and (more pointedly) what is meant by "valid"? (to wit <ahem>, I don't know if quarter-wit should be considered "valid")

I suppose you could take any word with a number or size and "adjust" the size, usually with the object being to intensify. e.g., joe is likely to do this task in a full-assed manner; teD has posted another of his thrice-told tales; etc.

<<double dare>>

Dear wwh,

A dare would downsize your challenge.

>we should check OED, but W3 traces it from ME wetewold as in cokewold (cuckold).

OED2 not only supports this, but suggests a direct path from cokewold, and shows the second sense as transf. (? with pun on wit-all.) One who has little sense; a half-witted person; a fool; occas. a witling.
Shakespeare was an early user of the cuckold sense.

I, too, remember double dare from my childhood (which predates Truth or Dare by a considerable amount). In my neighborhood the person who was double dared usually claimed that it meant that the issuer of the dare had to perform the required feat first.
