What do these eight words and/or phrases have in common?

No, any pronunciation similarities in my list are coincidental.

They all contain punctuation?

  • There’s a backwards comma in hammock.
  • There’s a check in checkup.
  • There’s an & in backhand.
  • And the i’s and j’s have a period on their tops.

…I’ll show myself out…

They all contain one or more of the 5 least used letters? (j, k, q, x, z)

That’s true… and in fact quite closely related to the more specific connection.

They all contain the ‘k’ sound?

They all have the same Scrabble score?

You got it! Twenty points.

OK, what do these 8 words have in common?

prise
plate
smith
anode
real
bung
hung
whig

OK, hint: the same 3-letter word can be inserted into each word to make another word.

Tin?

pristine
tinplate?
tinsmith?
antinode
retinal
bunting
hunting
whiting

Correct!

My list has only 6 items, because it is a complete list. If @Czarcasm would like to disqualify me and send me to the locker rooms and put someone else in, just let us know.

pop
six
squish
uh-uh
Cicero
Lipschitz

He had it comin’! He had it comin’!
He only had himself to blame.

The list is the refrain of the song Cell Block Tango from the musical Chicago.

Just beat me to it. Cell Block Tango

Railer, if you have a list, go ahead with it.

I’ve got one. Probably not too difficult, but here it is:

abandoned
abstention
airfreight
artwork
fourchette
heightened
misevent
scrawniness

Each word contains the name of a number.

This one’s even easier.

billiards
flourine
circles
cloud
tails
baseball
dressed
lives

Each relates to “nine”. 9-ball, atomic number 9, 9 circles of hell, cloud 9, cat of 9 tails, 9 innings, dressed to the 9s, 9 lives.

Sorry, I don’t have a list ready.

OK, I made one.

Ends
Evils
God
Hath
Human
Impel
These
While

These words are all found in the opening of the Declaration of Independence.

Is that it? If so, I’ve got one ready to go!
