phonetic determinative

Now if we look at the meaning of the five-rayed star (Fig. III-1,c,i) as an Egyptian hieroglyph [Gardiner, 1957, 487, symbols N13,14,15], we find that when the star was alone it was used as an ideogram or determinative (sometimes it was also used phonetically or as a phonetic determinative) in various words having to do with stars or constellations.
