Hey guys I am having trouble understanding the differences between
何をする and 何がする
The particles are confusing me, I understand both as "What are (you) doing"
Can someone be kind enough to shed some light on this problem???
Thanks in advance!!!
Neither one of these means "What are you doing?" The first can mean "What do you do?" The second is pretty funky.
I think you should just go over the difference between を and が more carefully, and you'll understand why the second sentence is funky (i.e., by knowing that が typically marks the subject rather than the object; by knowing that を is used to mark the object of volitional verbs like する; and so on).
It's weird, because if you use 何 in 何がする, one would expect an object and not a person to do the action of する (が is a particle that identify the subject of the verb it is linked to). Except that an object doesn't "do", basically you're asking "what object did that?", but you didn't even specify a "that". The question "What object did" is incomplete and calls for more information.
Like nadiatims said, with smells and sounds it could work.
何がそのいい香りをしてるの？ (lit) What is doing this nice smell?
Here we added そのいい香りを, which basically change the vague verb "する" (to do) to a whole verb sentence "いい香りをする" (to do a nice smell). Which makes sense for an object.
Regarding the difference between を and が, it's about what word is the subject (suffixed by が), i.e. doing the action, and what word is the direct object (suffixed by を), i.e. being subject to that action. The meaning is completely different.
