Learn Swedish: Ryttaren fokuserar mer på hoppningen än jag. - The rider focuses more on show jumping than I.

In Swedish, än (than) formally acts as a conjunction connecting two clauses. The full thought is än jag gör (than I do). Because jag is the subject of that implied verb, it stays in the subject form. While you might hear native speakers say än mig in casual speech, strict grammar rules require the subject pronoun jag when comparing who is doing the action.

Does fokusera always take the preposition på?

Yes, just like in English, the verb fokusera (to focus) pairs with på (on) to indicate what is receiving the attention. It is a fixed verb-preposition combination you should memorize together as fokusera på.

How is the noun hoppningen constructed?

It is built from the verb hoppa (to jump). Adding the suffix -ning turns it into a noun for the activity (jumping or show jumping). The -en at the very end makes it definite (hoppningen = the show jumping). Swedish often uses the definite form for general sports and activities where English leaves it indefinite.

The base word for rider is ryttare. Why is the definite form ryttaren and not ryttareen?
