Maybe Father's official statement after forgetting to fix that? (8,7)
I believe the answer is:
relative pronoun
'forgetting to fix that?' is the definition.
I can't tell whether this definition defines the answer.
'maybe father's official statement' is the wordplay.
I cannot really see how this works, but
'statement' could be 'pro' (pro is a kind of statement) and 'pro' is found within the answer.
This explanation may well be incorrect...
'after' is the link.
Can you help me to learn more?
(Other definitions for relative pronoun that I've seen before include "Maybe what" , "It could be that" , "Say which" .)
