Which spelling details matter here?
Compound numbers from 21 through 99 join the tens word and the ones word with a hyphen. In 3,891, the 91 part combines ninety and one, producing ninety-one. Hundreds are written by placing a digit word before hundred. In 3,891, the hundreds part is eight hundred. American English usually omits and after hundred when more digits follow. That is why this page writes three thousand eight hundred ninety-one without adding and before the final part. English reads large numbers in three-digit groups. 3,891 reaches the thousand group, so the group three is followed by the scale name thousand. Scale names stay singular inside exact number names. English writes three thousand without adding a plural s to the scale name.
