Why would you use a verbs stem (as state-of-being) rather than the verb itself?

Question

Now, I'm not sure if this has been answered, I looked but couldn't find a proper answer... so I ask. :)

While I was listening to this, I noticed the line 「空、翳{かげ}り」。Now, in the context of the song I of course understand what's being said (tho, 翳 was new to me), but I still don't quite understand why they would write 翳り、instead of 翳る or something like that?

This isn't the first time I've seen this of course, but I still don't quite understand why it's done; thus I ask.

Answer 1

翳り is the continuative form of the verb. in this form it gives the sense that there's more yet to be said.
