In these examples, [sensayng-nim-tul] and [cap-hi-si-ess-keyss-ta] consist of roots (sensayng and cap-), derivational affixes (-nim and -hi) and inflectional affixes (-tul, -si, -ess, -keyss andta), which can be safely assumed to be word-internal elements.
the elements outside the brackets can hardly be analyzed as either derivational or inflectional affixes.
