Cue for strike about direction (4)
I believe the answer is:
hint
'cue' is the definition.
(thesaurus)
'strike about direction' is the wordplay.
'strike' becomes 'hit' ('hit' can be a synonym of 'strike').
'about' means one lot of letters goes inside another.
'direction' becomes 'n' (N is an example**).
'hit' going around 'n' is 'HINT'.
'for' acts as a link.
(Other definitions for hint that I've seen before include "Tip - small amount" , "'Slight indication, indirect suggestion (4)'" , "Tip-off" , "Thin sort of slight indication" , "Clue - soupcon" .)
