Presence of the "s" at the end

Why are certain words (like five billion) written in plural while other words (like two thousand) are written in singular?

Hi Sara, 

It is because mille is invariable -

mille = one thousand

deux mille two thousand

cent mille = one hundred thousand

however, million and milliard are not, so will agree in number.

I hope this helps!

I think the answer is possibly lost in the mists of time. For no obvious reason that I am aware of «mille» is invariant and never made plural by adding 's'. All of the other 'large numbers' including millier(s) de, are made plural by adding 's' when required.  Expressing large numbers: thousands, millions and billions%252Fsearch%253Fs%253Dmilliers%252Bde
