Is “u” different when it’s followed by a single consonant than when it’s followed by a double one?
Is it more open when it’s followed by a double consonant, like the first one is more like german “ü” and the second one more like French “u” (more open though)?
Are all combinations of two consonants affecting “u” the same way, whether it’s the same consonant doubled (e.g. -ll- in skulle) or two different consonants (e.g. -nt- in “runt” or -ld- in guld)? Is it different depending on the combination?
If all of this is right, then is it also right that when “u” is at the end of the word (like in “du”) it’s pronounced like the one followed by a single consonant?
What else is there to know about the pronunciation of Swedish “u?”
