kau

[And Rosta <a.rosta@UCLAN.AC.UK>]

Can someone tell me where {kau} is discussed in Woldemar? - Or
if not, can someone tell me what it means?
I mean {kau} in general, not just after question words.
I seem to recall that originally kau was introduced for some
more general purpose and only latterly became restricted
in usage as a marker of indirect questions.

[I ask partly because I am wondering whether it could somehow
be used for specific veridicals.]
