Father and teenager at odds (8)
I believe the answer is:
generate
'father' is the definition.
(synonyms)
'teenager at odds' is the wordplay.
'at odds' indicates anagramming the letters.
'teenager' with letters rearranged gives 'GENERATE'.
'and' is the link.
(Other definitions for generate that I've seen before include "Produce, electricity say" , "evolve" , "Engender" , "Produce (energy, etc)" , "Create (power)" .)
