Oh, sorry rebyidd, seems like you were “shvitzing” over this very hard “ketzos”, for over a year. Whew!!
Me too. I just thought of a “mehalech”, a theory, hypothesis, explanation in those very cryptic words. Could be ZK was taught writing, spelling and also mathematics (and maybe other things too).
And ZK was subtly conveying to the OP the benefit (need) of using good writing skills. – my own theory.
