Learn Icelandic: Nokkrir einstaklingar æfa oftar en aðrir. - Several individuals practice more often than others.

The word aðrir is the masculine plural nominative form of annar. It takes this form because it refers back to einstaklingar (individuals), which is a masculine plural noun acting as the subject of the sentence.

The lesson focuses on contrasting sumir (some) with aðrir (others). Can we use nokkrir instead?

Yes! While sumir means "some", nokkrir translates to "several" or "a few". Both words pair perfectly with aðrir to contrast different groups of people. Since einstaklingar is masculine plural, we use the masculine plural form nokkrir.

How is the word oftar (more often) formed?

oftar is the comparative form of the adverb oft (often). Just like in English where you add "-er" to make a comparison, in Icelandic you often add -ar to the base form of an adverb.

What role does en play here?

In this sentence, en means "than". It is the standard word used in Icelandic to link two parts of a comparison, placed right after a comparative word like oftar (more often).
