I can think of three ways to use the second person reflexive.
- The first is to address someone else. You might be disgusted with a friend and say
How can you live with yourself?
- The second is the third person indeterminate, in which the pronoun doesn't refer to any one particular person. So you might read an ad that says
You will have yourself a wonderful time on our four day, two night
cruise to Santo Diablo.
This is in the second person, but they're clearly not talking to you because you're too smart to travel to some place called Santo Diablo. It's a substitute for the third person, which sounds stilted: "One will have himself a wonderful time."
- Thirdly and occasionally, an author will use second person narrative. Off the top of my head, the only example I can think of is Bright Lights, Big City by Jay McInerney:
You see yourself as the kind of guy who wakes up early on Sunday
morning and steps out to cop the Times and croissants.
That's the protagonist of the story talking about himself, and it's a detached way of speaking in the first person.
Few people would think either that dictionary entries are for them alone or that a dictionary has a narrator, so the third person indeterminate is unlikely to confuse.
