Question

how do you pronounce riu? As in Hotel Riu

Answer 1

Riu

Well, the two weak vowel together would form a diphthong so Riu is a single syllable word. The stress in a two weak vowel diphthong falls on the 2nd vowel so the "u" would be stressed.

I'd give you a phonetic spelling, but those are often confusing. It would be better to give you another word with an iu diphthong and tell you to pronounce the word similarly. Try ciudad.
