"He has a white hat."
Translation:Han har en vit hatt.
They can both be ’hat’, though a mössa is either a (knitted) one you wear in the winter that usually covers your ears (as in Canadian Eng. tuque, a beanie or a knit cap), or some sort of cap like the Swedish graduation cap which is called studentmössa. Hatt is more like a cowboy hat, a high hat, a sun hat or a panama hat or similar.
My understanding was that "de" was placed before an adjective + noun (like "vit hatt"). When is this used and not used?
I thought this too. I wrote "Han har den vita hatten. " I was so sure I remembered all the rules; the adjective becomes plural. But I think I may have actually written, "He has the white hat" which would have been definitive form.
I have a question about the Swedish "i" sound. I have heard it in bil, vit, and many other words where it sounds like it is stressed or there is something in your mouth while you say it. For example, in this video, you can hear the Swedish girl on the right say "bil." It is called "Language Challenge Italian vs. Swedish" by Tia Taylor. It is on YouTube. Does anyone know why or how to pronounce it? Tack så mycket.
