Concatenative morphology is affixal. The morphemes are arranged in a nice neat linear sequence, one after the other.
Non-concatenative morphology involves internal changes to the stem. The morphemes do not follow one another sequentially; they are mixed in together. The classic example is Semitic languages, in which triconsonantal roots are inflected by inserting vowels between the consonants. The morphemes are enmeshed within the roots, and are not easily separated from the roots.
Lâ Spîki must have non-concatenative morphology. The change from <ùkti> to <ketîsûþ> cannot be a matter of simply slapping affixes on.
-facepalm- never realized you posted that....lol i get distracted too easily! sorry!!!
lol yea <ketîsûþ> comes from <ùkti> which means "warrior".
the <ù> is removed to form the core-form <kti> which means "a warrior did something"
placing <e> between the consonant cluster shows the tentative mood; <keti> means "a warrior had the capability to do something"
inserting <îs> before the final <i> shows the chance; <ktîsi> means "there is almost a 100% chance the warrior did something"
the <i> (which still means "third person past tense") is changed to <û> (which means "second person future tense"); <ktû> means, "you, a warrior, will do something"
the final <þ> shows the aspect; <ktiþ> means "a warrior will have started doing something"
put them all together and you get <ketîsûþ> meaning "there is almost a 100% chance that you, a warrior, will have the capability to start doing something"
