Is it possible to reverse engineer a private key back into mnemonic?

Question

Is it possible to reverse engineer a private key back into mnemonic seed if it is not hard derived?

Is the private key using subkey derived from the mnemonic in a soft way? if so can the mnemonic be known from the private key?

If the mnemonic is hashed to produce the private key then you can't. — Decentration, Mar 17 at 16:47

Nope. Private keys derive from the mnemonic. A mnemonic can generate a lot of private keys. You can also check the HD wallet spec.

It's a one-way function like you said. Maybe it's a hash function. You can't recover the mnemonic from the private key.

Is it so? How does the mnenomic then recreate my private key?

Use the one-way function. M -> P: f(x) = y, P -> M: f(y) != x.
