Father and mother perhaps coming from opposite directions? That's clear (8)
I believe the answer is:
apparent
'clear' is the definition.
(synonyms)
'father and mother perhaps' is the wordplay.
'father' becomes 'ap' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'and' is a charade indicator (letters next to each other).
'mother perhaps' becomes 'parent' (mother is a kind of parent).
'ap'+'parent'='APPARENT'
'coming from opposite directions? that's' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for apparent that I've seen before include "Readily perceived" , "Seeming true; obvious" , "See 1" , "Noticeable" , "Obvious, clearly understood" .)
