TOI (http://www.lojban.org/en/publications/reference_grammar/chapter19.html)

Elidable terminator for TO. The right discursive parenthesis.

doi lisas. mi djica le nu to doi frank. ko sisti toi do viska le mlatu O Lisa,
I desire the event-of ( O Frank, [imperative] stop! ) you see the cat. Lisa, I
want you to (Frank! Stop!) see the cat.
