Consist of directions to follow (6)
I believe the answer is:
entail
'consist of' is the definition.
(I've seen this in another clue)
'directions to follow' is the wordplay.
'directions' becomes 'en' (I've seen this in other clues).
'to follow' becomes 'tail' (both can mean to chase or pursue).
'en'+'tail'='ENTAIL'
(Other definitions for entail that I've seen before include "Estate settled" , "Have as a logical consequence" , "settle estates for the long term" , "Involve or require" , "Call for" .)
