Bootstrap chain
Bootstrapping is the process of using a language's own compiler to compile a new version of itself. The very first compiler must be written in another language; once functional, that compiler can compile a self-hosted version. Delphi uses Pascal as part of its bootstrap chain.
See the guide on what is compiler bootstrapping for a walkthrough of how bootstrap chains work in practice.
