Questions & Answers about Min ven er sjov, når han synger.
In Danish, the possessive pronoun must match the grammatical gender and number of the noun:
- ven (friend) is a common-gender noun: en ven
- For en-words (common gender, singular), you use min
- For et-words (neuter, singular), you use mit (e.g. mit hus – my house)
So it must be min ven, not mit ven.
There are two main uses of adjectives in Danish:
Attributive (before a noun):
- en sjov ven (a funny friend)
- et sjovt hus (a funny/odd house)
- sjove venner (funny friends)
Predicative (after er, bliver, ser ud, etc., describing the subject):
- Min ven er sjov. (My friend is funny.)
In predicative position like in er sjov, the base form sjov is used and does not change for gender or number. So:
- Min ven er sjov.
- Mine venner er sjove. (here sjove matches plural venner)
In your sentence, sjov describes min ven via the verb er, so the form sjov is correct.
