archaic or rare adjective meaning skillful, manual, or relating to the right hand or side.
From Latin dexter (right) with -ical suffix. An older adjective form that largely disappeared as 'dexterous' became the standard English word for manual skill.
Dexterical is a ghost word—it shows up in some old texts but English speakers abandoned it for 'dexterous,' which comes from the same Latin root but became the clear winner in our language evolution!
