In a conversation with a fellow Ancient Greek enthusiast, the name "Medusa" (Μέδουσα, "ruling") came up. I made a rather tortured pun by switching the epsilon to an eta, creating μὴ δοῦσα.
Now, μή is a negative particle, and δοῦσα is a participle from δέω, "bind". I dimly remember using μή, rather than οὐ, with participles. But is this particular construction grammatical? If so, what would it mean?
