Learn Swedish: Vi tävlar på racerbanan så ofta som möjligt. - We compete on the race track as often as possible.

To say 'as [adjective/adverb] as possible' in Swedish, you use the pattern så + [word] + som möjligt. While English uses 'as... as...', Swedish uses så... som... (literally 'so... as...'). Here, the adverb ofta (often) goes right in the middle.

Why is there a -t at the end of möjligt?

In this fixed construction, you always use the neuter form möjligt, never möjlig. You can think of it as referring to an abstract, invisible 'it' (meaning 'as it is possible'), which forces the adjective to take the neuter -t ending.

Why do we use the preposition på before racerbanan?

Swedish generally uses på for locations that are open surfaces, floors, sports fields, or tracks. Because a racerbana (race track) is an open surface for driving, you compete på it. The noun is also in the definite form, ending in -n, giving us 'on the race track'.

If I moved så ofta som möjligt to the start of the sentence, how would the word order change?
