Well, what should be clear is that “nuh” implies the same vowel as “muh”, which I don’t think is the case for how “cinema” is normally pronounced. And I presume that it’s clear that “neh” is not pronounced the same as “nuh”. My point was not to indicate a precise pronunciation, just that I don’t see how “nuh-muh” would be right.
In addition, I personally can’t write IPA and be sure it’s correct, and I would expect that most people also can’t read it.
And also, I love this thing; upvote every time. For sharing terminal stuffs its loads better than copying the relevant bits and/or outputs from `screen` (do folk still use that?).
