Questions & Answers about Þau hlaupa hraðar í skóginum.
Why is hraðar used here for "faster"? What is the base word?
Hraðar is the comparative form of the adverb hratt (fast). Since it describes how they run, it is an adverb rather than an adjective. In Icelandic, many adverbs form their comparative by adding -ar, so hratt becomes hraðar (faster).
Why use Þau for "They" instead of Þeir or Þær?
They are running (moving), so why does í trigger the dative case (skóginum) instead of the accusative?
The preposition í takes the dative case when it describes a fixed location. Even though running is an active movement, the action is happening entirely inside the forest. If they were running into the forest from the outside, you would use the accusative case (í skóginn).
