Questions & Answers about Hún er ósammála mér.
Icelandic pronouns change form according to case. For ég (I), the main forms are:
- ég – nominative (subject)
- mig – accusative
- mér – dative
- mín – genitive
The adjective sammála / ósammála always takes the dative case for the person you agree or disagree with. That’s why you must say:
- Hún er ósammála mér. – She disagrees with me. (dative)
*Hún er ósammála mig is ungrammatical.
In English, you say disagree with someone. In Icelandic, the idea of with is built into the adjective ósammála, which governs the dative case instead of using a preposition:
- ósammála + dative = disagree with
So Icelandic just says:
- Hún er ósammála mér. – literally “She is disagreeing-to-me” (using dative), no extra word for with needed.
Ósammála is an adjective, not a verb. The verb in the sentence is er (the 3rd person singular of – ).
