>I have no idea what NG or TINW is<
Jackie, I've never heard them before either.
My guess is that they stand for 'network group' and 'those in (the) network' respectively. I'm working from context.
Which brings me to the only reasonable guideline I can think of - within context, it should be possible to work out (more or less) what the new coining means. (Note I'm thinking of everyday words here, rather than scientific etc.)
Which reminds me of Jabberwocky, which is of course always quoted in discussions on coining words.
'Twas brillig and the slithy tove
did gyre and gimble in the wabe.
All mimsy were the borogroves
and the mome raths outgrabe.
I have a question - what part of speech is 'outgrabe'? I have mused about this off and on for years (yes, I know I am a sad individual!) and still cannot decide whether it is an adjective or the past tense of a verb. My gut says 'verb', as in give/gave, but my brain insists that there is no English verb with a 'b' in that position and leaves me unconvinced.
Opinions, anyone?
