I am a non-native English speaker and sometimes it is very hard to understand the way how inversion happens in sentences.
What inversion does happen with the first sentence below when through every window is moved to the beginning of the sentence? And is the inversion a matter of a must or choice?
Light is coming in through every window. I don't think I can sleep here.
Through every window ???. I don't think I can sleep here.
Couple of my guesses are below.
Through every window is light coming. I don't think I can sleep here.
Through every window is coming light. I don't think I can sleep here.
Any explanations will be appreciated. Thank you.
