 An Ethereum-based blockchain can use the pre-block feeding strategy to migrate to Substrate.
 In the post-block generation model, the Ethereum block is generated *after* runtime execution.
-In the pre-block feeding model, the Ethereum block is feeded in *before* runtime execution.
+In the pre-block feeding model, the Ethereum block is fed in *before* runtime execution.
 
 A blockchain can first use pre-block feeding with empty extrinsic requirement.
-In this way, because no other external information is feeded, combined with a suitable consensus engine, one Ethereum block will have an exact corresponding Substrate block.
+In this way, because no other external information is fed, combined with a suitable consensus engine, one Ethereum block will have an exact corresponding Substrate block.
 This is called the [wrapper block](https://corepaper.org/substrate/wrapper/) strategy, and it allows Frontier to function as a normal Ethereum client.
 
 With a sufficient number of the network running a Frontier node, the blockchain can then initiate a hard fork, allowing extrinsic to be added in.
