In a shell language, that is “further processed” as literal text, except
for any instances of substitution markers.

in a programming language, you have the assumption that
“everything is a program construct until indicated otherwise”.

 
So what is  'for i in a ; do ... ; done'  then in your world?

“for” is just the name of a command, like any other. In POSIX, this one
happens to be built into the shell; it might not in other shells.
