Re: Assimilation - canīt
I agree with what Bob has said.
I don't think we can get anywhere unless we can find out what your teacher means by stop t, an expression that I, with a little knowledge of phonetics, have not met, though apparently Mike has. As Bob said, "The idea of something being 'left' is a romantic oversimplification".
It would be useful in future posts if we used phonetic/phonemic transcription for words being discussed.
