In Latin it is possible to create sentences from two identical words (homonym or homogram), or two minimal pairs.
Puro puro, I ritually purify with a bonfire.
Ēquus ĕquus, The horse is steady (aequus, even, steady, becomes medieval ēquus)
The only classical quote known to me that approaches this is Cicero's
O fortunatam natam me consule Romam.
"O fortunate state for my natal date and Consulate"...and he was assassinated soon after. Jingle and rhyme doesn't become acceptable until 400.
So, does anyone know of a collection of these two-word sentences.
If any more individual examples are known to you, I would be very happy to hear of them.
