Some trivial word puzzles

Without looking these up:

Wrought is the past participle of what common four-letter verb?

Taxicab is a contraction of what two nine-letter words?

Name a four-letter contraction of “That is the”. Note: it’s slang but well-known.

Wrought = past participle of “work”

Taxicab = taximeter cabriolet

The first two work for me. As for the third:

dat’s?

No, not “dat’s”…‘cause you’d still have to say “the” to make it a proper ebonic sentence…or at least “da”, as in
Dat’s da nine, da forty, da be-yotch n’ da Gee.

How about “this”?

I’m going to post the answer to the four-letter contraction question at about three- or four-o’-clock (Eastern time) if no one gets it by then.

I got it from a crossword puzzle in the Boston Globe some years back, and it stuck in my mind.

Hint: there’s no apostrophization.

Adda

Damn it, I just thought of that (although I was spelling “atta” as in “atta boy”) and by the time I made my back to the thread, Chrome Spot beat me to it.

[sub]I bet no one believes me, but it’s true, so there[/sub]

WAG: hist?

Correct! Although, yeah, the spelling most often encountered is atta.

Would a victory dance be appropriate now?
