Delicate use of words (4)
I believe the answer is:
tact
'delicate use of words' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for tact that I've seen before include "Skill in dealing with people" , "Sensitivity in dealings" , "Diplomacy or discretion" , "Sensitivity (in dealing with others)" , "Sensitivity, diplomacy" .)
