Yees.

Long E sound with a plural S on the end.

"EEs"

Don't pronounce the Y as a consonant.

Ees I guess. Like Y is ee in Spanish.

Eas. Like "ease", but with an "s" instead of a "z".

Edit: Seems like that is the "official" Wikipedia pronunciation. http://en.wikipedia.org/wiki/Ys_(series)

(Mouse over the symbols to get the gist of it).

You know when you get to the end of Fatal Fury and Terry Bogard goes "GEEEEEEEESE!" but it's really hard to make out with the sound quality so it just sounds like he's saying "EEEEEEEEEEEES"

Like that.

I thought is was Ease or Esse. No Y sound at all.

iss.

Why

Had to vote other since the proper pronunciation was not an option. Ravenlight got it right on.

Like wisp but with more y and less p.

Imagine "east", but without the "t".

Supercalifragilistic.

haha, this is the perfect description.
Alright, awesome, thanks everybody, I'll stop pronouncing it incorrectly :)

ees

I always thought this was pronounced "ee-s" as well.

ees

Is

Rhys.

A long "e" and then a short "s".

Like "east" only minus the "t". Kinda.

This is a pretty accurate description of how I say it, and it's the way I hear most people familiar with the franchise say it.

Bingo.
