The picture that proves the involvement of the tongue to the Scandinavian - the picture snake on the page 49r
As you can see the word"orm" denotes a snake or a worm and with Scandinavian languages and translated "snakes, worm".
In modern language the word is left unchanged, and so it is written - "orm", but, for example, in Old Norse it is "orm" written as "ormr" (Added to the end "-r")
