This is more of a spelling tip this  week and of course we'll talk about  

how to pronounce the sound, but the  question revolves around the letters c  

h and how do we know how they are pronounced. So  let's go ahead and take a look. Okay so we have  

two letters typically these two letters stand  for one sound and that's the ch sound or the ch.

So to make that ch sound what you're going  to do is you're going to touch the tip of  

your tongue to the back of your top front teeth  and then the tongue pulls back for the ch ch/

You can see my lips are slightly rounded and  we see this in words like cheese and much. 

So again this is the default pattern.

We have two exceptions for you. We have the k sound and this is in words  

that are more greek in derivation and again two  letters are going to be one sound the K. To make  

a k sound tip of the tongue is low in the mouth  back of the tongue is pull up air just puffs out  

and we see this pattern and the  word chemistry stomach and school.

And then last we have these two  letters ch pronounced as the  

sh sound the s h sound again typically two letters  accounting for one sound for this sound your lips  

are rounded your tongue is not touching your  teeth and the air just continues to move out. 

We see this in words again  typically a french derivation  

in words like champagne and machine and mustache.

So again we have three ways  to pronounce the letters c h

The overarching general rule is we're going  

to pronounce this as CH and we see  that in words like cheese and much

and we can also pronounce them like a k sound  when they're in more of a word that comes from  

greek and we would see that in  chemistry stomach and school

and then last sometimes we  pronounce these letters as an sh  

in champagne machine and chicago  my state my hometown i'm sorry um 

and the reason we do this is because  those are more french in derivation
