Can we omit the subject and object at the same time?
Although he is hurt by her, he still loves her. (nothing omitted)
Although hurt by her, he still loves her. (subject omitted only)
Although he is hurt, he still loves her. (object omitted only)
Although hurt, he still loves her. (subject and object omitted )
I was taught about dropping the subject, but never know something about dropping the object, so I wonder which we should omit in priority, or if we should omit them at the same time, when the main clause and the dependent clause have the same subject and object.
