I'm writing something and there are several places where I need to use multiple adjectives.
I've always learnt that multiple adjectives should always be separated by a comma, but my supervisor said that they should only be separated by a comma if they are different.
So whereas I would say:
We present a novel, industry-inspired problem [...]
He argues it should be:
We present a novel industry-inspired problem [...]
What is the complete rule regarding multiple adjectives and commas? Thank you.
