1. You guys should have had this guy killed.
2. You guys should have had killed him.
3. You guys should have killed him.
Sentence number two is not correct.
1. You guys should have had this guy killed. - This means it was advisable for "you guys" to hire someone to kill "this guy", but "you guys" didn't for some reason. It could also mean that it was a good idea - advisable - for you guys to ask someone to kill "this guy". It doesn't have to mean that "you guys" had to hire someone. "You guys" could have asked someone from within the "organization" to kill "this guy". Someone from within the "organization" would already be on the payroll, so "you guys" wouldn't have had to hire someone to kill "this guy".
3. You guys should have killed him. - This means that it was advisable, or a good idea, for "you guys" to kill "him", but for some reason "you guys" didn't do it.
2. You guys should have had killed him. - This is not correct.
to have "someone" do something - Here, "have" is being used as a causative verb. It is used with the past modal form "should have + past participle". In this case the past participle is "had", which is also the verb. The object pronoun "him" should follow "had".
should have had him killed
Here's another example so that you can compare.
Your car is going to cost more money to fix now. You should have had it checked out as soon as you thought something was wrong.
You should have had it checked out. - correct
You should have had checked it out. - not correct
Here, the object pronoun also has to follow the causative verb "had", which is a past participle following "should have" - should have had it checked out
Are these correct? If not, why? What does it mean?
1. I have dry skin.
2. I have dried skin. (If it is incorrect, why no present perfect here?)
In other words,
1. My skin is dry, as opposed to moist. :D
2. My skin has been dried by a process.
Note that, for example, meat is dried, giving dried meat. The skin of an animal can be dried, too, giving dried skin (i.e., a dried pelt), but human skin is 'dry'; if dried (i.e., dried out of its moisture) it means, the skin is no longer living). :wink:
