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.

In particular, it is not used at the end of subordinate texts quoted with lu … li'u or parenthesized with to ... toi .
