Cursive hieroglyphs should not be confused with hieratic. Hieratic is much more cursive, having large numbers of ligatures and signs unique to hieratic. However, there is, as might be expected, a certain degree of influence from hieratic in the visual appearance of some signs. One significant difference is that the orientation of cursive hieroglyphs is not constant, reading right to left or left to right depending on the context, whereas hieratic is always read right to left.
