only use generic build system terminology

we will use a translation table to introduce nix-specific terms

 At the top is the *command line interface*, translating from invocations of Nix executables to interactions with the underlying layers.
 
 Below that is the *Nix language*, a [purely functional programming](https://en.m.wikipedia.org/wiki/Purely_functional_programming) language.
-It is used to compose  expressions which ultimately evaluate to *derivations* — self-contained *build plans* to derive new data from referenced input data.

 ::: {.note}
 The Nix language itself does not have a notion of *packages* or *configurations*.

+As far as we are concerned here, the inputs and results of a derivation are just data.
 In practice this amounts to a set of files in a file system.

 The command line and Nix language are what users interact with most.
 
-Underlying everything is the *Nix store*, a mechanism to keep track of derivations, data, and references between them.
-It can also *realise derivations*, that is, *execute build instructions* to produce new data.
+Underlying everything is the *Nix store*, a mechanism to keep track of build plans, data, and references between them.
+It can also execute *build instructions* captured in the build plans, to produce new data.
 It uses the file system as a persistence layer, and a database to keep track of references.
 
 This chapter describes Nix starting at the bottom with the store layer, working its way up to the user-facing components described in the rest of the manual.
