In Nordic languages (Swedish, Norwegian, Danish, Finnish), 'Y' is always a vowel sound, similar to saying English "ee" (like in "week") but with tightly rounded lips, often described as a "duck face" or a mix between "ee" and "oo". It's a high, front, rounded vowel (IPA: /y/ or /yː/), distinct from English 'Y' and varies slightly in length (short vs. long) depending on the following consonants.
