Would it be possible to improve the error message here in the word codec? I haven't looked at the relevant part of the code to debug what the possible types of errors there are though, but the current error message isn't helpful for debugging what a user did wrong. (Though the cause of the error might be unclear)

For context, I was running:

$ democli keys add test --recover
Enter a passphrase for your key:
Repeat the passphrase:
Enter your recovery seed phrase:
apple banana cat dog
