How do I say words with "ton" and "tan"?

Another great question today from a You Tube Subscriber:

“Please do a video about how to pronounce the word importance¨ and another one about the word that finish in Ton like Clinton, Washington, Wilmington, etc. Thank you! Your videos have been very helpful. “

Think of the ending pronounced as “TIN”. The ending is not stressed so it is shorter than the other syllables: CLINtin, WASH-ing-tin, WILL-ming-tin.   The same pronunciation:  “TIN” applies to the word “importance”.  

Thanks for the question and best of luck!
