Where are the terms? "derivation path" originate

BIP-32 does not mention that term. "derivation path" However, a quick search (https://bitcoinsearch.xyz/?search=derivation+path) returns a lot of results, so you have to make assumptions. "derivation path" It is part of the Bitcoin language.

I would like to ask you two questions:

1. is "derivation path" What is the correct term?
2. So where does this word come from (is it specified or just colloquial)?

thank you
