Learn Finnish: Minun on vaikea hyväksyä tulkintaasi, koska se on epäkohtelias. - It is difficult for me to accept your interpretation, because it is impolite.

This is the genitive experiencer structure you are currently learning. When expressing how someone evaluates an action (like finding it difficult, easy, or nice), the person experiencing it goes into the genitive case (minun). This is followed by on, the evaluative adjective (vaikea), and the action in the basic infinitive form (hyväksyä).

Would the adjective vaikea change if the experiencer were plural, like 'It is difficult for us'?

No, the adjective does not change. In this specific evaluative structure, the verb is always in the third-person singular (on) and the adjective stays in its basic nominative singular form. So, 'It is difficult for us' would simply be meidän on vaikea.

Let's break down the word tulkintaasi. Why is it in this form?

It comes from the noun tulkinta (interpretation). Here it is in the partitive case (tulkintaa) because the verb hyväksyä (to accept) is acting on an abstract concept, making it an ongoing or abstract action rather than a physically completed whole. Then, the second-person singular possessive suffix -si (your) is added directly to the partitive ending.

Does se in the second clause refer to the situation or the interpretation?
