Danish consonants have properties that make them different from those of other Germanic languages. Word-initial consonants are always voiceless but can be voiceless aspirated or voiceless unaspirated. Word-final consonants are always voiced, and voiced consonants can also occur in consonant clusters with a voiceless alveolar fricative.
The word bil means car. It has a voiceless unaspirated consonant. The word pil means arrow and has a voiceless aspirated consonant.
In the word sort (black), the final consonant is voiced. It is the consonant /d/. However, it is partly devoiced. The words bæk (brook) and kop (cup) end with the voiced consonants /g/ and /b/.
Consonant clusters with the voiceless alveolar fricative combine with voiced plosives. For example, the words skole (school) and busk (bush) have the consonant cluster /sg/. In sprog (language) and stol (chair), the consonant clusters are /sb/ and /sd/.
In most languages, consonant clusters agree with one another in voicing. The English word books has two voiceless consonants in the coda and dogs has two voiced ones. However, Danish allows the combination of a voiceless consonant and a voiced consonant. This is not the case in Norwegian and Swedish, two similar languages.
Danish only allows voiceless consonants at the beginning of the word and only allows voiced consonants at the end. The combination of a voiceless /s/ and voiced plosive occurs in consonant clusters. In languages such as English, such a combination is not possible. Danish consonants are thus unique.
