It is possible to combine the Locative Forms of the Noun with the Plural
Form of the Noun to create Locative Plural Forms.  These forms are
composed of 5 parts:

Noun Prefix + Noun Base + Linker Vowel + Locative Suffix + Plural Suffix
 

5.1. External Locative Plural Form

The External Locative Plural Form is created by adding the Plural Suffix
onto the end of the External Locative Form of the noun.  Note, however,
that in this construction, the Plural Suffix always takes the short form
-shö, and not the long form -shö'ö.

   Ø-    -ënish-     -æ-   -'ke-   -shö   ënishæ'keshö     on the shelves
   ka-   -'seht-     -a-   -'ke-   -shö   ka'sehta'keshö   on the cars
   u-    -nö'ka-     -æ-   -'ke-   -shö   unö'kææ'keshö    on the horns
   Ø-    -ahtahkw-   -a-   -'ke-   -shö   ahtahkwa'keshö   on the shoes
 

5.2. Internal Locative Plural Form

The Internal Locative Plural Form is created by adding the Plural Suffix
onto the end of the Internal Locative Form of the noun.  Note, however,
that in this construction, the Plural Suffix always takes the short form
-shö, and not the long form -shö'ö.

   ka-   -nöhs-     -a-   -kö-   -shö   kanöhsaköshö     under the houses
   ka-   -'seht-    -a-   -kö-   -shö   ka'sehtaköshö    under the cars
   ká-   -yatösh-   -æ-   -kö-   -shö   káyatöshæköshö   under the books
   ka-   -(h)ösh-   -æ-   -kö-   -shö   kaöshæköshö      inside the boxes

Note that although the Internal Locative suffix has a long vowel when it
occurs at the end of a word, as in «kanöhsakô» "under the house", it
always has a short vowel when followed by the Plural suffix.
