Could anyone convince me of the correct pronunciation of the word APPRECIATE.

I, along with most of the English speaking world, happily pronounce it appreSHiate...but I heard the other day someone pronouncing it appreSiate ie using an S sound rather than SH..Their justification was that it is derived from the French word 'Appreciez'...and therefore would be an S sound....Anyone give any credance to this??

All suggestion welcome.

/&-'prE-shE-"At/, /-'pri-/ also /-'prE-sE-/.
If you go to www.webster.com you can put in that word and hear how it's pronounced according to Webster's Dictionary...I did, and it's definitely with the "sh" sound.

"appreSHiate" is correct. Not only as to me, pronounce it that way for more than 10years but also i heard many native English speakers pronouce it that way.

So i guess this is the correct way to pronounce it!
