The Blackfeet Creator is Na'pi (Old Man). This is the word used to indicate any old man, though its meaning is usually loosely given as white. An analysis of the word Na'pi, however, shows it to be compounded of the word Ni'nah (man), and the particle a'pi, which expresses a color and which is never used by itself, but always in combination with some other word.
The Blackfeet word for white is Ksik-si-num' while a'pi, though also conveying the idea of whiteness, actually describes the tint seen in the early morning light when it first appears in the east. The dawn is not a pure white, but has a faint cast of yellow. Na'pi, therefore, would seem to mean 'dawn-light-color-man,' or 'man-yellowish-white.' This is also the color of many old men's hair.
