The sequence of words is: to, tre, fire, otte, ni, ti, elleve, tyve, enogtyve, toogtyve, treogtyve, ...

In Danish, when pronouncing a two-digit number, the last number is mentioned first; for example, '21' is "enogtyve" ["one-and-twenty"], and '121' is "ethundredeogenogtyve" ["one-hundred-and-one-and-twenty"].

All numbers ending with 02, 03, 04, 08, 09, 10, 3n, 4n, n00, or n000 will end in a vowel.

Please note that '100' can be both spelled and pronounced as "hundrede", "ethundrede", "hundred" and "ethundred"; similarly, '1000' can be spelled "tusinde", "ettusinde", "tusind" and "ettusind". The "et" in "ethundrede" is often omitted in daily speech.
