[lojban-beginners] "don't do that"

[Luke Bergen <lukeabergen@gmail.com>]

so, last night chatting in the irc channel got me thinking about common phrases that a lojbanic parent might say often enough to their child.  Given that, one that I came up with that I couldn't figure out a good lojban equivalent of is "don't do that".

In lojban it seems like this might be something like {ko na cu tu'a ta} but I'm not sure you can do things like that with tu'a.  Basically I want something that means {you imperitive, do not now or in the future do the event <that>}.  With {tu'a} we can say {meh, the abstraction that you know I mean when I say ____} but how would you (or can you) do that with pointing words like {ti}, {ta}, {tu}?  And if not, how would you say what I am trying to say?  Given that the child may have already ceased doing what (s)he has been doing or may still be doing it.

maybe another way might be {ko na co'e zukte}?
