Many words can have variants, regarding spelling. Some words vary in spelling depending on location, for instance 'honour' and 'honor'. Some words behave this way because one people keep to a more traditional spelling, while another adapts for pronunciation change. Words such as 'catalogue' and 'catalog', or 'dialogue' and 'dialog' are examples of this phenomenon. However 'prologue' and 'prolog' are not synonymous, even though it would appear they should be.
