-t (adverbium)
Adverb -t
In Danish, you can turn most adjectives into adverbs by adding the suffix -t. This describes how something is done.
How It Works
To describe the manner of an action, Danish typically uses the adjective's base form plus a -t.
1. Regular Formation:
Most adjectives simply add -t.
- langsom (slow) → langsomt (slowly)
- pæn (nice) → pænt (nicely)
2. Adjectives ending in -t or -e:
If an adjective already ends in -t or -e, it does not change when becoming an adverb.
- let (easy) → let (easily)
- stille (quiet) → stille (quietly)
3. Adjectives ending in -ig and -lig:
When these describe how an action is performed (manner), they take -t. However, when they modify another adjective (degree), -t is optional in standard writing as well as speech.
- Manner: Han taler tydeligt (He speaks clearly).
- Degree: Det er rigtig koldt (It is really cold).
4. Adjectives ending in -sk:
- -isk and Nationalities: These do not change. Han spiller fantastisk (He plays fantastically).
- Short -sk words: One-syllable words like frisk or rask do take -t: Det blæser friskt (There is a brisk wind).
5. Word Order:
In a standard sentence, the adverb usually follows the verb it describes. See verb-second word order for more on sentence structure.
Check the stem: A form already ending in -et does not gain another t. Likewise, keep the e in simpel → simpelt: Han forklarede det simpelt (he explained it simply). Do not confuse this with the plural adjective simple, which loses the stem e. Final vowels can take t in particular words: ny → nyt, fri → frit; Du kan vælge frit means you can choose freely. God → godt supplies the usual manner adverb (she sings well: hun synger godt). Vel is a separate adverb/particle with uses such as probably or surely; it is not a mechanical replacement for godt.
Current -ig/-lig rules: Manner uses require t. Degree uses modifying another adjective or adverb allow both forms, as in rigtig/rigtigt koldt; this is a standard spelling choice, not just informal omission. Degree words standing independently require t. Time adverbials normally require t too (for example årligt, tidligt); the seven exceptions with optional t are bestandig, evig, foreløbig, idelig, nylig, samtidig, sluttelig.

- Hun taler hurtigt.
She speaks quickly.
Word by Word: She speaks quickly.
The adjective 'hurtig' (quick) becomes the adverb 'hurtigt' to describe how she speaks.
- Barnet sover tungt.
The child sleeps heavily.
Word by Word: The child sleeps heavily.
The adjective 'tung' (heavy) becomes 'tungt' to describe the manner of sleeping.
- Det blæser friskt i dag.
There is a brisk wind today.
Word by Word: There is a brisk wind in day.
Non-nationality monosyllabic adjectives ending in -sk, like 'frisk', take the -t suffix when used as adverbs.
- Det er rigtig koldt i dag.
It is really cold today.
Word by Word: It is really cold today.
When an -ig/-lig word is used as a degree adverb (modifying an adjective like 'koldt'), -t is optional in standard writing as well as speech.
- Han synger fantastisk.
He sings fantastically.
Word by Word: He sings fantastic.
Adjectives ending in -isk (like fantastisk) do not take a -t when used as adverbs.
- Hun sidder helt stille.
She sits completely still.
Word by Word: She sits completely still.
Adjectives ending in -e, like 'stille', do not add a -t when used as adverbs.
Common Mistakes
Adding -t to adjectives ending in -isk.
De spiller fantastiskt.De spiller fantastisk.Adjectives ending in -isk (like fantastisk, typisk, ironisk) and nationalities (like dansk) never take the -t suffix as adverbs.
Forgetting the -t on short -sk adjectives like 'frisk'.
Det blæser frisk.Det blæser friskt.Unlike -isk adjectives, short one-syllable adjectives ending in -sk (like frisk or rask) take the -t suffix.
Spelling 'let' with a double t (the Norwegian spelling).
Opgaven er lett gjort.Opgaven er let gjort.'Let' already ends in -t, so the adverb is the same word: let gjort. Danish spells it with one t; 'lett' is the Norwegian spelling. Adjectives that end in -e (like 'stille') also stay the same as adverbs.
How It Connects
Learn This First
To understand how to form adverbs from adjectives using the -t suffix, you first need to be familiar with basic adjective usage and the neuter gender suffix -t, which shares the same form. You also need to know basic verb conjugation to see how the adverb modifies the action in a sentence.
- Adjective After Være
Understanding how adjectives function as predicates is essential before learning how they can be transformed into adverbs.
Level 1 - -t (intetkøn)Neuter Adjective -t
The adverbial -t ending is morphologically identical to the neuter adjective ending, so familiarity with this suffix is a key prerequisite.
Level 2 - -rPresent Tense -r
Adverbs typically modify verbs, so a basic understanding of present tense verb conjugation is necessary to form complete sentences using adverbs.

Another suffix used to form adverbs, often for more abstract concepts (e.g., heldigvis).

Meget is a common adverb used to intensify other adverbs (e.g., meget hurtigt).
