HI!

When you say "thirty-nine hundred", it is 3900, right?

• Absolutely correct. The hyphen in thirty-nine is optional - I never use it.

mmmm... Interesting!!! as I have learnt, but I would like someone to clarify this... that we should use hyphen when writing numbers from twenty-one (21) up to ninety-nine (99)**?

In this case, when you have the word "hundred" after it, or in the case of "thousand", then... the hyphen is optional?

twenty-three
twenty three thousand
twenty-three thousand??? This number is higher than ninety-nine?? (23000 is higher than 99)**, then this should be: twenty three thousand, without the hyphen.

I'm going to confess that my habit of not hyphenating numbers between 21 and 99 is probably wrong, although I don't think it's that uncommon. I'm hoping, though, that someone will back me up and agree that, as time progresses, it has become optional. Any takers?

There is definitely no hyphen before "hundred" (even if I'm wrong on the other point): thirty-nine hundred.

I don't understand your question about ninety nine I'm afraid. Can you elucidate?

Hi el escoces!!!

I just edited my previous posting to make it clearer(I hope so!!!). The reason I mentioned 99 is that I know numbers from 21 up to 99, when written in letters, those should have hyphen (twenty-nine, eighty-two, etc.), and if you hyphen twenty three thousand (twenty-three thousand), for my understanding, this could be wrong as 23000 is higher than 99.

But I am not assuring this, I just want someone to clarify ...

Ah I see! Well, thousand is a unit (or each thousand is a separate unit) and you have twenty-nine of them, just like saying twenty-nine dogs or twenty-nine million (to stick to numbers). Does that make sense?
