I always understood it as this

Transpilation: text to text (eg: Scheme to C)

Compilation: anything to anything but usually it implies text to binary code

transpilation is compilation but compilation is not necessary transpilation (the all squares are rectangles but all rectangles ...)

[pjmlp]

So classical UNIX C compilers are now transpilers, because they always did text to text (C to Assembly), before forking to the assembler.

The first AIX C compiler called itself a "transcompiler" in it's manual, so yes, they are.

[pjmlp]

Any digitalized version of it available online?

[shakna]

Not that I know of.

But you can see the term of the day, "translator", here[0][1], and it isn't much of a leap to see how that evolved into translator-compiler, and then shortened itself.
