The ledger's three words
Every clause in Somka carries one of three ledger words: ka (kept, done), kha (struck, not) and na (pending, not yet). Before a verb, ka means it has been done, na means it will be, and kha means it is not.
Ne ka ri
I done cross
I have crossed.
Ne na ri
I pending cross
I will cross.
Ne kha ri
I not cross
I don't cross.
A verb with no ledger word in front of it is simply now, or always: Ne ri, I cross. There is no other tense. Time is counted in nights.
