One shouldn't jump to conclusions though. They may not be the fastest thing on four legs, but from my observations tortoises gobble their food down pretty damn quickly!
I'm trying to grab the theory. Adding the "t" to långsam makes it an adverb?
Exactly! Note that the t-form can also be an adjective (when used with ett-nouns):
en långsam sköldpadda
ett långsamt djur
sköldpaddan/djuret äter långsamt
FYI: "Sköldpaddan" should have the stress on first syllable) and all vowels should be short (Nov 21, 2014).
Exactly :). The Swedish word is similar (well) to the German though:
sköldpadda = Schildkröte
where sköld = Schild = shield and padda = Kröte = toad
Is there a different word for tortoise? I thought in Swedish they were the same?
What is the difference? In french it's the same word, I see those two words everywhere in english and still don't know what they really mean
There are some differences, but the main one is that turtles live in water (at least some of the time), whereas tortoises are land dwellers!
Sköldpadda can mean either. If you want to be specific, you can say havssköldpadda (sea turtle) or landsköldpadda (land turtle).
Although landsköldpaddor can ONLY be tortoises (in British English at least -- where the word turtle refers exclusively to the marine reptile).
A tortoise lives on land, while turtles live primarily in water; but will travel on to land sometimes.
A toad is alike a turtle like an egg to a chestnut, I wonder who was the one to name this animal a toad with a shield
No, I'm afraid they're not even remotely related. "Tror" is a verb rather than an adverb and means "believe(s)".
