Thanks in advance for your help. I'm new to the czech language and have been practicing with Pimsleur audio CDs. One thing I have noticed and been unable to find an explanation for: In some words the letter "t" seems to be pronounced with a "k" sound - as in the english word "key". Examples: velmi mě těší : něco k pití In both of these phrases the "t" seems to be pronounced like "k" by the czech speaker. Is this a trick of my english ears? Is there a rule for when "t" should sound like "k"?
