"Marti(it)al Arts"

       Why do I keep reading "martial arts" as "marital arts"? 

       I much prefer love to war, that is for sure. 

       I think also I see the two as somehow linked.  The marital arts may at times urge either partner to ponder the need for martial arts.   And do the martial arts at times depend upon all the grace and finesse that the marital arts can muster?

       Mixing the two indeed suggests there are arts to the marital state and to sustaining it.

       And raising the skills of combat to the level of "arts" has granted mayhem a luster and finish to take pride in?
