Adverbs are generally made by putting an ending -t to an adjective. If the adjective ends with a d, then the d is changed to a t, except when the vowel has a shorter length, then it becomes -tt. Historically, it would have become -dt no matter what, this is still the case in Danish. If the adjective ends with a t, one adds a new t and shorten the length of the vowel. If the ending is -n, then the n is changed into a t.

Note however, that also adjectives acquires the same ending if the noun is neuter instead of uter. The comparative and superlative forms are the same as for an adjective.
