Pre-particles (IPP) are a very small class of elements, much like preverbs and prenouns, but which can attach to other elements in the derivation of additional indeclinable particles (IPC).

The examples in (1) through (4) illustrate four of these fairly rare pre-particles.

(1)    kapē- “all, throughout”: kapē-kīsik “all day”; kapē-tipisk “all night’; kapē-pipon “all winter”
(2)    awasi- “beyond”: awasi-otākosīhk “day before yesterday”, awasi-wāpahki “day after tomorrow”
(3)    akāmi- “across”: akāmi-sīpīhk “across the river”; akāmi-tipahaskān “across the border”
(4)    kēkā- “almost”: kēkā-mitātaht “nine”; kēkā-nīsitanaw “nineteen; almost twenty”

In even rarer cases, these elements may also function as particles themselves (as in 5), or serve as the root from which other particles (6 and 7) can be derived:

(5) kapē   “always, for the full duration”
(6) akāmāyihk “across the way, at the other side of a place” (from akāmi-ayihk)
(7) kēkāc  “almost, just about, nearly”
