Can someone explain Japanese language rule?

Question

I've noticed that if the word is spelled suk or zuk and a vowel following it that the u is silent. Is there some rule for this?

Answer 1

The "U" is never really silent; You can think of it as whispered. If a speaker is enunciating very clearly, declaiming poetry, singing, etc., you will hear it. In ordinary speech, it almost disappears at the end of a word, or before a following t, k, p, etc. Listen to more spoken Japanese, and you'll pick it up easily.  

Answer 2

Japanese people silence NO vowels, since every sound is important in Japanese. You will notice that when you listen more.

Answer 3

its not actually silent.. but native speakers hardly pronounce it.

if you are not a native speaker (which i guess ur not..) then i would suggest pronouncing it as if you dont, people may have trouble understanding you.

this is similar with shimasu (and other desu/masu endings) the u is not pronounced. however it is more extreme in these cases..
