How does Icelandic word stress differ from stress patterns in borrowed Scandinavian words?

In the context of Scandinavian languages, stress patterns differ significantly between Icelandic and other languages in the group.

In most Scandinavian languages, stress is typically placed on the first syllable of native words, but borrowed words often retain stress on a later syllable. In contrast, Icelandic maintains a consistent rule where stress is placed on the first syllable of all words, regardless of their origin. This rigid adherence to initial-syllable stress is a distinct feature of Icelandic, whereas other Scandinavian languages allow for exceptions in borrowed vocabulary.1
