That’s a fascinating angle—Sparta’s “krypteia” wasn’t just a purge, it was a linguistic cloak. They’d whisper the same name, “Spartiates,” to each other, but use the Doric form that enemy Macedonian commanders didn’t recognize. It was like a secret code that made a messenger seem like a local, letting them slip through patrols. I’ve been tracing how that same phonetic trick turned the Battle of Leuctra, letting the Spartans sneak a surprise flank in plain sight. It’s all about the sound shifting the perception of allegiance, not just the words.
