Hello folks, it's basically to do with how you pronounce words when there are 2 consonants together, I'm having a hard time thinking how to explain this but: 'regretted' is pronounced 'regr-eh-tted' because of the two 't's. If it had one 't' it would be 'regreted' which would be pronounced 'regr-E-ted'. 'floppy' is pronounced 'fl-o-ppy' whereas 'flopy' would be pronounced 'fl-O-py' 'shipping' is pronounced 'sh-ih-pping' whereas 'shiping' would be pronounced 'sh-eye-ping'. it's as if the two consonants at the end shorten the sound of the vowel before them. If anyone has any idea what I'm trying to explain, do you know if there is a rule that states this? Thanks in advance.
