What is the nuance of the plural kunskaper? Is it saying "He has only superficial knowledge across a range of topics? "Jack of all trades and master of none".
The g in "ytliga" is pronounced when the woman says the sentence; but mute when you tap the word to listen to it again.
In relation to that: I know pronunciation of g is a funny thing in Swedish, especially in adjectives. Is there a simple rule for that (e.g. "you never pronounce the g in plurals of -lig adjectives"), or do you know where I can read more on the topic?
Before a consonate or hard vowel (a, o, u, å), is like g in English. Before a soft vowel or at the end of a word, it's pronunced similar to English y. There is also the ng sounds, which appears in words like många.
So the plural form of ytliga should have hard g sound, and my guess it's a bug. Hopefully a native speaker can confirm.
TIL you can click a word on Duolingo... wish I'd known that a few years ago.
I'd actually either not pronounce the g at all here, or just very faintly. The TTS voice has it correct. But I wouldn't hazard a guess about ratios.
