pronunciation of är
is är pronounced like "are" or "air" in american english because the ä sounds different in är from the ä in ägg and i assumed that ä would be pronounced generally the same as it is in german which would make är sound like "air" in american english but "är" is said like "air" in the voice thingy on duolingo help
To be honest I just stick with saying "eh", which is how I've heard that people in the Stockholm region say it. It's more comfortable to say it like that, and I've heard it like that (videos, music, etc), so I'm sticking to it. That "are" or "air" sound makes it too awkward for me.
They have the same accent. All monosyllabic words have the same accent.
The phonemicity of this tonal system is demonstrated in the nearly 300 pairs of two-syllable words differentiated only by their use of either grave or acute accent. Outside of these pairs, the main tendency for tone is that the acute accent appears in monosyllables (since the grave accent cannot appear in monosyllabic words) while the grave accent appears in polysyllabic words.
See my comment above for the difference between ä and ä followed by r.
"De e" is basically how you pronounce "det är". Where I'm from we tend to say it more like "dä ä", like Zmrzlina mentioned.
Dig/mig is the old, and still considered the only correct way of writing it. However, since it's such a weird spelling a lot of people tend to write it as it's spoken when texting and chatting and whatever. That is, they write "dej/mej".
