Confused on を,し,and をし

I keep getting confused on を,し,and をし. I can never tell when to use either one or the two together. Can someone explain their use? They all seem to be used in front of verbs.

November 2, 2017



As I understand it, some nouns have a special する-verb status that allows them to be used with する (or します) without を. Nouns that don't have this status have to have を, but nouns with this status can be used with or without を.

If you look in a dictionary, it'll usually say if a noun is a する-verb.


Thank you, that was something that wasn't clear to me.


Yes! Jisho does this and it's my dictionary of choice.


I think you mean を plus します, right?

I struggle with that too: sometimes を is there (べんきょうをします), sometimes it isn't (テニスします). I asked this same question about 何をしますか and got some helpful replies but haven't internalized them enough to be able to repeat them. I'll see if I can dig up the link.

Yes, that is it. Thank you for the link!


を、し do not usually go together. I suggest that you give some examples which you have find confusing for more relevant answers.


In that case I would reply in the older thread.
