Questions & Answers about Vem har tränat flitigast för loppet?
How do we form the superlative adverb flitigast (most diligently)?
The base word is the adjective flitig (diligent). To make it a basic adverb, we add -t to get flitigt (diligently). However, for the superlative ("most") form, regular adverbs drop that -t and just add -ast to the root, giving us flitigast.
Is flitigast acting as an adjective or an adverb in this sentence?
It is an adverb! Adjectives describe nouns (like a diligent person), but adverbs describe verbs. Here, flitigast describes how the person trained (har tränat). For regular words, the superlative adverb looks exactly the same as the superlative adjective.
Why is the verb spelled tränat instead of träna or tränar?
Because it follows the helping verb har (has). Together, har tränat makes the present perfect tense ("has trained"). Träna is a regular Group 1 verb, so we form this past-tense form (called the supine) simply by adding a -t to the end.
Why does loppet end in -et?
