"我要跟你商量一件事情。"

Translation: I need to discuss something with you.

[hippietrail]

Would the Chinese be different for "I want to discuss ..." than for "I have to/need to discuss ..."?

[Cinnamon5230]

Yes, since 要 can be both "want" and "will", you need to replace it with other words.

我想…… I want to ...

我需要…… I need to ...

我必须…… I have to ...

[hippietrail]

So does that mean that this question can also correctly be translated into "I want to discuss something with you"?

[brian.g.chen]

"have to/need to" would be more like 需要. If you put "want to", it should have been accepted.

[n7RD4]

1 issue or 'an issue' or 'a matter' should be acceptible.

[KX3.]

"I want to discuss something with you" is accepted.

[linmn]

Is this version of discuss more business focused or can it be used to describe discussions in general about any topic?

[jamtintraders]

"I need to discuss a matter with you" s/be accepted

[deactivated user]

Agree... this answer was rejected to me as well.

[Jacques439990]

"I want to discuss this with you" should have been accepted, right ? Or am I not?

[deactivated user]

On pleco dictionary 事情 is also translated as "matter"

[Elijah.Fung]

I need to discuss a thing with you 不行吗

[deactivated user]

It looks correct, but I think most people would say "something" rather than "a thing."

[SharaStar2]

我要跟你商量一动物事情。

Dong wu is not suitable?

[BobbyTable2]

I don't believe so. 动物 (Dòngwù) means "animal"
