## 5.5. Complex tanru with
*ke* and
*ke'e*

The following cmavo are discussed in this section:

ke |
KE |
start grouping |

ke'e |
KEhE |
end grouping |

There is, in fact, a fifth grouping of
“pretty little girls' school” that cannot be expressed with the resources explained so far. To handle it, we must introduce the grouping parentheses cmavo,
*ke* and
*ke'e* (belonging to selma'o KE and KEhE respectively). Any portion of a selbri sandwiched between these two cmavo is taken to be a single tanru component, independently of what is adjacent to it. Thus,
Example 5.26 can be rewritten in any of the following ways:

**Example 5.31.
**

ta | ke | melbi | cmalu | ke'e | nixli | ckule |

That | is-a-( | pretty | little | ) | girl | school. |

**Example 5.32.
**

ta | ke | ke | melbi | cmalu | ke'e | nixli | ke'e | ckule |

That | is-a-( | ( | pretty | little | ) | girl | ) | school. |

**Example 5.33.
**

ta | ke | ke | ke | melbi | cmalu | ke'e | nixli | ke'e | ckule | ke'e |

That | is-a-( | ( | ( | pretty | little | ) | girl | ) | school | ). |

Even more versions could be created simply by placing any number of
*ke* cmavo at the beginning of the selbri, and a like number of
*ke'e* cmavo at its end. Obviously, all of these are a waste of breath once the left-grouping rule has been grasped. However, the following is equivalent to
Example 5.28 and may be easier to understand:

**Example 5.34.
**

ta | | melbi | | ke | cmalu | | nixli | ke'e | | | ckule |

That | is-a-( | pretty | type-of | ( | little | type-of | girl | ) | ) | type-of | school. |

Likewise, a
*ke* and
*ke'e* version of
Example 5.27 would be:

**Example 5.35.
**

ta | melbi | | cmalu | ke | nixli | | ckule | [ke'e] |

That | is-a-(pretty | type-of | little) | ( | girl | type-of | school | ). |

The final
*ke'e* is given in square brackets here to indicate that it can be elided. It is always possible to elide
*ke'e* at the end of the selbri, making
Example 5.35 as terse as
Example 5.27.

Now how about that fifth grouping? It is

**Example 5.36.
**

ta | melbi | | ke | | cmalu | | nixli | | | ckule | [ke'e] |

That | is-a-pretty | type-of | ( | ( | little | type-of | girl | ) | type-of | school | ). |

That is a beautiful school for small girls. |

Example 5.36 is distinctly different in meaning from any of Examples 4.2 through 4.5. Note that within the
*ke*…*ke'e* parentheses, the left-grouping rule is applied to
*cmalu nixli ckule*.

It is perfectly all right to mix
*bo* and
*ke*…*ke'e* in a single selbri. For instance,
Example 5.29, which in pure
*ke*…*ke'e* form is

**Example 5.37.
**

ta | melbi | | ke | cmalu |

That | is-a-pretty | type-of | ( | little |

| ke | nixli | | ckule | [ke'e] | [ke'e] |

type-of | ( | girl | type-of | school | ) | ). |

can equivalently be expressed as:

**Example 5.38.
**

ta | melbi | | ke | cmalu | | nixli | bo | ckule | [ke'e] |

That | is-a-pretty | type-of | ( | little | type-of-( | girl | type-of | school | )). |

and in many other different forms as well.
