Several hundred years ago, V was both a consonant and a vowel. Over time it evolved into V being a consonant, U being the vowel, and the sound that was 'VV' became W, which is why it's pronounced 'Double U' but looks like two V's. That might not be entirely right, but I believe I'm close. You'd have to look up the evolution of the latin alphabet I suppose. Edit: So to answer your question, I believe it's pronounced 'subtle' :)
