As far as I know, we can omit "being" in the sentence 1 and 2.
1- He smiled at his girlfriend, her clothes (being) all muddy and tattered.
2- His Ipad (being) dead, he felt bored.
Can I omit the "being" in these sentences below as well? If I cant, what is the difference?
3- I was preaparing the food , my friends being sick of waiting. (I was preparing the food and my friends were sick of waiting)
4- The word “book” has a double meaning , the noun form being "a set of pages inside a cover”, while the verb form is "to arrange to have a seat etc. at a particular time in the future".
