Commutative, or "semantically palindromic" sentences

Now that I've played around with this, the only way it can work is if the subject and the direct object are the same; otherwise, it will reverse the actions.

I drove myself.

Myself drove I.

While it sounds weird, it does mean the same thing, unlike this case, where the DO is different.

I drove Jerry.

Jerry drove I.

Watch this watch

Unless I've misunderstood the question, of course.

EDIT: And in case using the same first and last word is cheating, how about

Path a route (eg. through a maze)

The reverse form still makes sense, just about, I think.

Essentially for an A-B-C structure you'd need pairs of words that are both nouns and verbs, and have the same meaning in both senses. It's an interesting thing to think about.

My first thought was "Listen, you!" It works both ways. It's short and simple (like me.)

"Right are you." "You are right." (Many words can be substituted for "right," e.g., "married;" & other pronouns for "you," e.g., "they are happy" / "happy are they.")

One of the sentences I, an eleven year old, found that stays the same backwards is:

mr owl ate my metal worm

... and backwards it is still:

• mr owl ate my metal worm.

Am I as bored as you are? Are you as bored as I am?

The words, intact, are maintained in both directions. The meaning is the same but the words are different:

Is it crazy how saying sentences backwards creates backwards sentences saying how crazy it is?

I

Go

A is A.

Wasted days are days wasted.

I have just attended a seminar entitled "speech-accompanying gestures". "Gestures accompanying speech" would have the same meaning, I think. Not a sentence, though.

Never a foot too far even split to this: neve raf oot toof a reven (Split it apart backwards)
