TECH: QUERY on ZI & ZEhA

[Mr Andrew Rosta <ucleaar@UCL.AC.UK>]

(1) Does "cazu" mean "a long way back in time and a long way forward
in time", so that "mi ca zu cmalu" means "I have been small for
a long time & will continue to be small for a long time"? Or must
I use "ca zehu" for this?

(2) What is the difference between "ro roi" and "zehe"?

(3) Do ZAhO and ZEhA serve to separate a sumti from the selbri,
the way CU does?
(I don't at all understand the rules for when a sumti terminates.)
