Definition of mnemonic phrase
A Mnemonic phrase is a series of unrelated words, usually 12 or 24 words long, that can be used to regain access to a cryptocurrency wallet. It can be seen as a backup key for the wallet for when you lose access to it for whatever reason. A mnemonic phrase is often also referred to as a private key or seed phrase.
