Daughter to take part in ramble -- father reviewed plan (4,3)
I believe the answer is:
road map
'plan' is the definition.
(I've seen this before)
'daughter to take part in ramble father reviewed' is the wordplay.
'daughter' becomes 'd'.
'to take part in' means one lot of letters goes inside another.
'ramble' becomes 'roam' (synonyms).
'father' becomes 'pa' (pa can mean dad or father).
'reviewed' says the letters should be written backwards.
'pa' backwards is 'ap'.
'd' put into 'roam' is 'roadm'.
'roadm'+'ap'='ROAD-MAP'
(Other definitions for road map that I've seen before include "What may help one get around" , "Guide" , "sort of plan" , "superseded by satnav?" , "Driver's chart showing routes" .)
