My ESl freind asked me a question that I couldn`t quite answer and is bugging me. I hope you guys can help.
What is the grammatical difference between these verbs (not the difference of meaning between the sentences)
1. he HAD WALKED his dog
2. he HAD his dog WALKED

What is the grammatical difference between these verbs (not the difference of meaning between the sentences)
1. he HAD WALKED his dog
2. he HAD his dog WALKED

The second sentence is grammatically a causative one

It is made as follows:

Have + something (noun)+ past participle

[Casiopea]

Additionally,

1. He HAD WALKED his dog (before he ate dinner).
=> past perfect; two events connected in time. The event that happened first takes had -ed morphology.

2. He HAD his dog WALKED.
=> He had someone walk the dog for him. That is, he didn't walk the dog, someone else did it.
