On the level of word-shape, the phonotax of a language is a first determinant of its style, but the pattern of distribution within that frame is perhaps of equal importance.

Finally, names more or less adapted to Greenlandic phonotax will show a few deviations from the declination paradigms: e.g. Suulut ought to become Suulutip in ergative like t-stems use, but will become Suulup.
