Questions & Answers about Hann er jákvæður og duglegur.
Why do the adjectives end in "-ur" here, and how would they change if the sentence started with "Hún"?
The adjectives jákvæður and duglegur both end in -ur because they are in the masculine singular nominative form to agree with the subject hann (he). If the subject were feminine (hún), these strong adjective endings would drop, making the sentence Hún er jákvæð og dugleg.
Does "duglegur" strictly mean "hardworking" like in a job context?
Not just that! Duglegur is a highly versatile and culturally significant Icelandic word. While it means hardworking or diligent, it is also used broadly to mean energetic, capable, or doing a good job. For example, Icelanders frequently use it to praise children or pets, similar to saying someone is being a very good boy or girl.
