So it surprised me when Electrum generated some seed words that had more than one possibilities when writing down word (the words were GROUp - GROUnd and COMMit - COMMon.
In that case, when restoring to Electrum, pay attention to the suggested word's highlight:
- If it's highlighted in yellow like this: commit, it belongs to Electrum's old wordlist which isn't used to generate new Electrum seed phrase or in BIP39.
- If there's no highlight, it belongs to BIP39 wordlist which is the same wordlist used by Electrum by default.
E.g.:

Do you know maybe when creating new seed in Electrum if by chance I get all words that are BIP39 compatible (without "special" words unique for Electrum word list) can I recreate that seed on BIP39 wallet?
Of course I would not gamble like this with funded seed, to try to recreate it on uncompatible wallet, but I'm just curious if it is possible.
