Questions & Answers about Han sprang så fort att han fortfarande är anfådd.
How does the så ... att structure work in this sentence?
It expresses a consecutive degree, meaning a cause and its result. Just like so ... that in English, så (so) modifies the adverb fort (fast), and att (that) introduces the result of him running so fast: he is still out of breath.
Why does fortfarande come before the verb är here? Usually the verb comes second!
Because att han fortfarande är anfådd is a subordinate clause (a dependent clause). In Swedish, sentence adverbs like fortfarande (still) or inte (not) must come before the verb in subordinate clauses. This is often taught as the BIFF rule.
Could I use snabbt instead of fort here?
Yes, you absolutely can. Both fort and snabbt mean fast or quickly, and they are completely interchangeable when describing an action like running. The main difference is that fort is only an adverb, whereas snabb can also be an adjective.
What kind of word is anfådd?
It is an adjective that means out of breath or panting. Because it describes han (a singular en-word subject), it ends in -dd. If the subject were plural, such as they, you would add an -a to the end and say de är anfådda.
