Firstly, I'll assume stop, close, and quit are synonymous, at least in the following discussion that have the same meaning. We often see these phrases, especially on our phones when an app's not working. My question is how to use this phrase properly?
Some people treat this phrase as a noun, for example a sentence I got from a google book:
If the application died with a forced close, you are probably missing one of the needed assets.
Or as an adjective, this example is from Quora:
Just open force stopped application. Now, your force stopped application start running.
Or as a verb, this one is from a game forum on Reddit:
...and suddenly the game forced closed...
And quite few people use it as two separate verbs:
How to force an app to quit on your Mac
Those different usages confuse me, particularly, which part of speech is it? And how to use it?
