I'm revisiting my old question [#167151]. The original question was about the word order: “dear my love” or “my dear love”. I hold a position that we say “my dear love”.
But when I was saying a prayer yesterday, I heard myself say “dear my lord”, and it just sounded smooth to my ear. I looked up the phrase and I found it in Hamlet by Shakespeare. That made me think, what was in my mind when I asked the former question.
The linked site above for Hamlet lists line-by-line translations into modern English and the page shows the following dialogue in Act 3, Scene 2, Page 2:
[Shakespeare] CLAUDIUS: Thanks, dear my lord. [Translation] CLAUDIUS: Thanks, my dear lord.
And my question here is not about which order is correct. Instead I wonder: If the word order was turned the other way around, when did the change occur, and why did it happen?
