Could we say that when saying the 'tr' in words like 'train', 'tram' etc, that the /t/ and /r/ often coalesce to make a sound which is more similar to 'tchr'?
I myself definitely do this, but I have not found it documented in any text books that I've read, tho' I'm sure I haven't read them all!
All thoughts/comments much appreciated.
PS. Apparently "Creating the new tag 'coalesence' requires at least '300 reputation." ...in case anyone is wondering why on earth I didn't tag this post properly.
