score is the slang for twenty

Oh dear senior moment a score is twenty

"Oh dear senior moment a score is twenty"

Not really a senior moment, Margot. The question was asked incorrectly. Twenty is not slang for a score; score is slang for twenty. The question should have been "For what number is score the slang?"

In fact it is arguable that "score" is not slang at all (in the same way that "gross" - 144 - is not). I believe its original use in Old English was something to do with counting sheep. When twenty had been counted a mark was scored on a tree to keep the count. It's where "scoreboard" and "scorecard" originate.

Proper slang terms for numbers (usually money) include a "pony" (£25) and a "Monkey" (£500).

I wouldn't refer to a score as slang either (except when £20 is referred to as a score, perhaps) so maybe the question has been mistranslated/mistyped at some point.
A jackson is slang for $20.
The slang for £20 is Bobby Moore or Apple Core

I agree that "score" is not slang. The King James Version of the Bible has (Psalm 90:10) "The days of our years are threescore years and ten .. "

Jonathan-Joe, I agree as you point out that score has a perfectly proper meaning but it also has a slang meaning as said.

[Jonathan-Joe]

Donny - "Score" is an old and proper word (NOT slang) meaning "twenty". Can you quote any authority that regards it as slang?

Danny - you've made your point (to anybody who regards that website as an authority).

[New Judge]

The original question made no mention of money. To say you have two score sheep is no more slang than saying you have two dozen eggs.

NJ forgot to include a Lady (Godiva) = Fiver.

[ToraToraTora]

apple core - Score
Cock n Hen - Ten
Lady Godiva - Fiver

>The original question made no mention of money.
Agreed, NJ. But the original question didn't make sense, as you intimated at 15:36, so some of us have suggested what the OP may have been trying to ask. I think you were the first one to refer to slang terms for money and some of us picked up on that
