Then you no longer have a language which can be implemented in a few KB.
You might as well use a real with with proper data types, and not have
the stack exposed in the language. Forth code can be very cryptic
because of that.

For me it's one of those languages, like Brainf*ck, which is trivial to
implement (I've done both), but next to impossible to code in.

I implemented a toy version, with 35 predefined words, that was enough

 OK, so apparently you missed essential part.

I've looked at half a dozen hits for 'forth postpone' and I still don't understand what it does. Apparently something to do with compiled mode.
I wouldn't know enough to confidently implement it or use it.
Another mysterious feature with hard to understand semantics. You did say this was a very simple language and trivial to implement in a few KB?
My opinion of Forth has gone down a couple of notches; sorry.
(I'm not against all stack-based user-languages; I was quite impressed by PostScript for example. But then I didn't have to do much in-depth coding in it.)

On ZX81? I can imagine it being hard! (Someone wanted me to do something
on ZX80, but I turned it down. I considered it too much of a toy.)

 To give more background, bare ZX81 had 1kB RAM (including video RAM).

You must mean /excluding/ surely? Otherwise there wouldn't be much left from 1KB!
The first Z80 machine I /made/ had 0.25KB RAM, to which I added 1KB (actually 1K 6-bit words; two bits unpopulated to save £6), of text-mode video memory.
The second version had 32KB RAM, the same 1K text-mode memory, and 8KB graphics-mode video memory. I was able to write my first compiler on that one, written using an assembler, which itself was written via a hex editor, and that was written in actual binary. ('Full-stack')
But both only had tape storage so tools were memory-based.
