Persist
PERSIST', verb intransitive [Latin persisto; per and sisto, to stand or be fixed.]
To continue steadily and firmly in the pursuit of any business or course commenced; to persevere. [Persist is nearly synonymous with persevere; but persist frequently implies more obstinacy than persevere, particularly in that which is evil or injurious to others.]
If they persist in pointing their batteries against particular persons, no laws of war forbid the making reprisals.
