Current implementations follow BIP39 and 32, you can read those to see how keys are derived from the words

Current blockchain.info wallets use the BIP39 wordlist, which you can find for various languages at <https://github.com/bitcoin/bips/blob/master/bip-0039/bip-0039-wordlists.md/>

Previous versions have used non-standard implementations with a variety of different wordlists for example [v2](https://github.com/blockchain/unused-My-Wallet/blob/master/mnemonic.js#L319-L534) and [v3](https://github.com/blockchain/unused-My-Wallet/blob/master/mnemonic_words_v3.html).
