I am one of your followers. even in lingots....this is quite a while ago you asked the above question and I -having begun with swedish lessons only in august 2017- am back to this kind of question again because I had stopped working for a month. Now I have the feeling that I don't know anything any more after having had the experience of not understanding a word when I heard swedes talk together. Where do you live? are you in Sweden? Why do you learn this language? I have met many Swedes and like them much. And as I have to do something for my brain (getting old) I have chosen to learn swedish. I love the way duolingo is in contact with us and felt very happy about it. Now it's such a disappointment that I seem to know nothing any more. Did you have similar problems from time to time? I would be very glad if you found these lines and gave me an answer. Kind regards from Karin (I am German and live in Morocco. French is my everyday-language)
Merriam-Webster lists it as an adverb and an adjective. It seems to be a flat adverb, as described here: http://www.quickanddirtytips.com/education/grammar/do-all-adverbs-end-in-ly. Saying "the cook talks funnily" sounds funny to me.
