Mnhei’sahe
“Gentlefolk,” [Romulan Subcommander] Tafv said…in his light tenor, “I assure you that the Commander is as little sanguine about offering you this plan as you are at the thought of accepting it. If it succeeds, the Commander and I have nothing to gain but disgrace, irrevocable exile for both of us and for the rest of her crew, and the permanent possibility of being hunted down and killed by Romulan agents for revenge’s sake.” He looked grave. “We are all willing to risk that for her sake. It’s a matter of mnhei’sahe.” There were curious looks around the table at the word the translator had failed to render, but Tafv didn’t stop. “However, we face far, far worse if the attempt fails. If caught in Romulan territory, we and Bloodwing‘s crew will assuredly die. You and your ships could conceivably fight your way out again—and whatever difficulties you may have with Starfleet Command afterward, you will still be alive to have them.”
“Noted, Subcommander,” [Captain James T. Kirk] said. “One moment. Lieutenant Kerasus—‘mneh’-what?”
“‘Mnhei’sahe,’” she said promptly. “Captain, I’m sorry, but you would ask me to render one of the most difficult words in the language. It’s not quite honor—and not quite loyalty—and not quite anger, or hatred, or about fifty other things. It can be a form of hatred that requires you to give your last drop of water to a thirsty enemy—or an act of love that requires you to kill a friend. The meaning changes constantly with context, and even in one given context, it’s slippery at best.”
“In this one?”
Kerasus glanced across at Tafv. “If I understand the Subcommander correctly, they are returning the favor that Commander t’Rllaillieu has done them by commanding them, by being in turn willing to be commanded. That sounds a little odd, I know, but their forms of what we call ‘loyalty’ do not always involve compliance. These people will follow her to death…and beyond, if they can…because they acknowledge that what she’s doing is right, no matter what High Command says.”
