The cmavo fa'o (of selma'o FAhO) is the usually omitted marker for the end of a text; it can be used in computer interaction to indicate the end of input or output, or for explicitly giving up the floor during a discussion. It is outside the regular grammar, and the machine parser takes it as an unconditional signal to stop parsing unless it is quoted with zo or with lo'u ... le'u. In particular, it is not used at the end of subordinate texts quoted with lu…li'u or parenthesized with to ... toi.
