discursive \dis-KUR-siv\, adjective:
1. Passing from one topic to another; ranging over a wide field; digressive; rambling.
2. Utilizing, marked by, or based on analytical reasoning -- contrasted with intuitive.

Discursive comes from Latin discurrere, "to run in different directions, to run about, to run to and fro," from dis-, "apart, in different directions" + currere, "to run."

Wikipedia

A word that can be used, depending on the circumstance, to mean both of two opposite concepts.

• Auto-antonyms are the same words that can mean the opposite of themselves under different contexts or having separate definitions
  • enjoin (to prohibit, issue injunction; to order, command)
  • fast (moving quickly; fixed firmly in place)
  • cleave (to split; to adhere)
  • sanction (punishment, prohibition ; permission)
  • stay (remain in a specific place, postpone; guide direction, movement)

Sanctions are frequently called for on the politcial stage and in the law. Sanction is one of those duplicitous words-- it can can mean both reward and punishment.

This is a type of word to avoid. You cannot count on you reader giving the same interpretation to the circumstances that you do. So you cannot be sure your meaning will be understood. Far better to choose a simpler word.
