Questions & Answers about Ég er mjög áhugasamur um myndlist.
Why does the Icelandic sentence use um when the English translation says "in"?
In Icelandic, the adjective áhugasamur is always paired with the preposition um (literally "about"). Fixed prepositions rarely translate perfectly between languages, so it is best to memorize them as a set: áhugasamur um + accusative case.
Does the ending of áhugasamur tell us anything about the speaker?
Yes! Adjectives always agree in gender and number with the person they describe. Áhugasamur is the masculine singular form, which tells us the speaker (ég) is male. A female speaker would say ég er mjög áhugasöm.
Since áhugasamur um takes the accusative case, why doesn't the word myndlist change its ending?
It actually is in the accusative case here! Myndlist (visual art) is a feminine noun. Many feminine nouns that end in a consonant have the exact same spelling in the nominative, accusative, and dative cases.
