Why are there two forms for the number 1?

Norwegian 1 agrees with the noun it counts. Neuter nouns take ett (ett hus), while common-gender nouns take en or stressed én (én mann). The gender selector lets you produce the correct trailing form.

Why is 21 written tjueen and not tjue en?

Norwegian joins tens and units into a single word. So 21 is tjueen, 35 is trettifem and 99 is nittini, written without spaces, unlike the older twenty-and-one ordering some languages use.

The connector og appears before the final group below one hundred when a larger group precedes it. For example 235 is to hundre og trettifem and 101 is hundre og én.

How large a number can it handle?

It spells numbers up to plus or minus 999,999,999, covering ones, tens, hundreds, thousands and millions. Larger values are reported as out of range.

This tool spells whole numbers in Norwegian Bokmål, getting the tricky parts right: the gender-dependent form of 1, the spaceless compound tens such as tjueen, and the og connector that links the final group in larger numbers.

How it works

The number is split into groups of millions, thousands and the remainder below one thousand:

Each group below 1000 is spelled with hundreds (to hundre), then og, then the tens-and-units part.
Tens and units fuse into one word: tjue + en becomes tjueen, tretti + fem becomes trettifem.
A trailing 1 uses ett for neuter nouns or én for common-gender nouns, based on your selection.
The groups are joined with tusen and million/millioner.

So 1234 with a common-gender unit becomes ett tusen to hundre og trettifire.

Example and notes

For 235 you get to hundre og trettifem; for 1000 simply tusen. The gender choice only affects how a final 1 is written, which matters because Norwegian numbers agree with the counted noun. Negative numbers are prefixed with minus.
