Newer Solidity 0.5.x compilers generate ABIs whose function and event parameters contain an internalType field as well as the usual type.

In the examples I've seen, type and internalType usually have the same value. But presumably that would not always be the case.

What is the meaning and purpose of this internalType field? When would it differ from the just-plain type field?

Thanks!

This post does a nice job explaining the difference. Basically, internalType provides useful debugging information but is not required for contract encode/decode. So for example, an input struct will have a type of tuple and an internalType of the struct's declared name.
