Understanding the Future Perfect in Danish Grammar

Formation of Future Perfect in Danish
In the Danish language, the future perfect tense combines the future tense of auxiliary verbs ‘at have’ (to have) or ‘at være’ (to be) with the past participle of the main verb. These verbs work together to convey actions that will be completed in the future.

Here’s the construction for future perfect tense in Danish:
– Subject + future tense of ‘at have’/’at være’ + past participle of the main verb

When using ‘at have’, the structure is depicted as follows:
– Subject + vil have + past participle of the main verb

In cases where ‘at være’ is employed, the verb structure takes this form:
– Subject + vil være + past participle of the main verb

It’s important to note that the choice between ‘at have’ and ‘at være’ as auxiliary verbs depends on the main verb being used. Transitive verbs generally use ‘at have’, whereas intransitive verbs require ‘at være’.

Examples of Future Perfect in Danish

To better understand the concept, let’s take a look at some examples using both ‘at have’ and ‘at være’ as auxiliary verbs.

Using ‘at have’ as the auxiliary verb:
1. Han vil have spist frokost. (He will have eaten lunch.)
2. De vil have set filmen. (They will have seen the movie.)
3. Vi vil have skrevet rapporten. (We will have written the report.)

Using ‘at være’ as the auxiliary verb:
1. Vi vil være ankommet. (We will have arrived.)
2. De vil være gået. (They will have left.)
3. Hun vil være blevet færdig. (She will have finished.)

Utilizing Time Expressions with Future Perfect

Time expressions are often used to provide context for the future perfect tense. These expressions help specify when the action will be completed. Common time expressions include ‘inden’ (before), ‘efter’ (after), and ‘når’ (when).

Examples of time expressions in future perfect sentences:
1. Inden de kommer, vil han have forberedt middagen. (Before they arrive, he will have prepared dinner.)

3. Når de vil have læst bogen, kan vi diskutere den. (When they will have read the book, we can discuss it.)

Applying Future Perfect in Questions and Negations

Asking questions with future perfect in Danish:

To form questions, simply switch the subject and the auxiliary verb’s position:

2. Vil de være gået hjem? (Will they have gone home?)
3. Vil hun have købt billetten? (Will she have bought the ticket?)

Negating future perfect sentences in Danish:

In order to negate a future perfect sentence, simply add ‘ikke’ (not) before the auxiliary verb.
