Daughter seen with runner in club (6)
I believe the answer is:
driver
'club' is the definition.
(type of golf club)
'daughter seen with runner' is the wordplay.
'daughter' becomes 'd' (genealogical abbreviation).
'seen with' means one lot of letters go next to another.
'runner' becomes 'river'.
'd'+'river'='DRIVER'
'in' is the link.
(Other definitions for driver that I've seen before include "See 1 down" , "Flat-faced golf club" , "Motorist - golf club" , "Golf club; chauffeur" , "Type of golf club" .)
