11. Exceptions occur due to compounding and other derivational processes. 12. Ottawa derivational morphology forms basic word stems with combinations of word compound words. 13. Nominal compounding is highly productive as a derivational process. 14. Otherwise, root reversal is not a meaningful derivational process in Semitic languages. 15. Similarly, Slavic languages have extensive morphophonemic alternations in their derivational and inflectional morphology, 16. They may also end in a derivational suffix. 17. Thus, in this usage, all derivational affixes are part of the stem. 18. Combinatorial constructions include both inflectional and derivational constructions. 19. Therefore existing examples rather resemble ordinary derivational prefixes. 20. The suffix "-o " is dropped immediately after the derivational suffixes.
