Questions & Answers about Är det lärorikt att testa metoden?
Why does the adjective end in -t (lärorikt) if there is no "ett" word in the sentence?
When you use an adjective to evaluate an action (like att testa metoden), the sentence uses det as a placeholder subject. Because det is a neuter pronoun, the adjective must take the neuter -t ending. That is why lärorik becomes lärorikt.
How is the word lärorikt formed?
It is a compound word made from the root of att lära (to learn) and the suffix -rik (rich). So something that is lärorik is literally "rich in learning," which translates to instructive or educational.
Could I rephrase this sentence without using det?
Yes! You can put the infinitive phrase first: Att testa metoden är lärorikt? (To test the method is instructive?). However, using det as a placeholder at the start makes the sentence flow much more naturally in everyday Swedish, just like using "Is it..." in English.
Could I use prova or försöka instead of testa here?
You could easily use prova (to try out / test), as it is very similar to testa in this context. However, you should not use försöka. Försöka means "to attempt" to do something, whereas testa and prova are used when evaluating a thing or a process, like metoden.
