Copula verbs are linking verbs which couple two or more elements together. For example, in ”The bear is big” the copula verb is links the subject the bear to the subject complement adjective big. In present tense utterances, copula verbs are semantically empty which means they don’t contain any information. In predicative clauses (sentences where the subject and the subject complement refer to the same entity) the copula verb is unnecessary. Therefore, speakers sometimes leave out the copula-verb er ’be’. There are two possible scenarios of this type: either the copula-verb is completely omitted – aka a copula drop – or the copula is embedded in the previous word, by lengthening of the last vowel of that word. Additionally, the copula verb can either be stressed or unstressed. Together, these four realizations form a continuum from ‘marked presence to ‘overt drop’. This continuum is illustrated below, together with examples and descriptions of the four realizations.

Omitted   Incorporated         Present       Marked presence 

<     <     <     <     <     <                              >     >     >     >     >     > 

Overt drop     Lengthening   Unstressed copula  Stressed copula 

Overt drop 

When the copula verb is omitted completely, it is called an overt drop. This is exemplified in the below example.

In line 1 we have a fully realized copula-verb, whereas in lines 2 and 6 there could have been a copula-verb after det ‘that’, but there isn’t. There is also no trace of a copula in the pronunciation of the adjacent words, where it could have occurred as an incorporated phonetic lengthening of the word. In line 2 the copula-dropped part of the utterance is constructed as a split sentence, which in Danish is a common way of emphasizing a specific sentence constituent. In this case, the sentence det jo ikk ligefrem kampe ‘it (copula drop) not exactly matches’, begins with det ‘it’, emphasizing the word kampe ‘matches’ in an assessing utterance. The copula drop in line 6 is also part of an assessing utterance. 

Lengthening 

Lengthening is when the copula verb is not pronounced as a separate word, but rather incorporated in the previous word which is lengthened. In the below example, the lengthening occurs in Maren’s introduction of herself, in the beginning of a phone conversation.

In this example the copula verb has become part of the previous word det ‘it’, which is lengthened to d:et. There is thus no separate copula-verb connecting d:et and the speaker’s name. This is illustrated with a colon after the lengthened vowel. The fact that er ‘is’ doesn’t have its own spot in the sentence is not treated as a problem by Johanne, because she immediately responds to her introduction with a greeting in line 5. 

Dropped copula and lengthened copula only exist in our data after personal pronouns and short adverbs ending in a vowel (det ‘it’, de ‘they’, je' ‘I’, du ‘you’, vi ‘we’, I ‘you PL’, så ‘so/then’, nu ‘now’).  

Unstressed copula 

As the name suggests, unstressed copula is when the copula verb is pronounced without stress. This variant of the copula is the one presented in traditional grammars of written language.

In the above example we find an unstressed copula verb right after han ‘he’. The only function of the copula verb here is to couple han ‘he’ and the following description bare så sød ‘just so nice’. The action performed in the copula clause is an assessment. 

Stressed copula 

Stressed copula is a present, separated, and distinct copula verb which is stressed and thus emphasized in relation to the remaining words in the utterance. In the below example we see a stressed copula verb in line 3. The stressed word is marked by underlining.
