In a manner of speaking I'd see a mishap (8)
I believe the answer is:
accident
'a mishap' is the definition.
(I've seen this before)
'in a manner of speaking i'd' is the wordplay.
'in' is an insertion indicator.
'a manner of speaking' becomes 'accent' (accent is a kind of manner of speaking).
'accent' enclosing 'id' is 'ACCIDENT'.
'see' is the link.
(Other definitions for accident that I've seen before include "Unfortunate unintentional incident" , "Chance event with no apparent cause" , "Prang" , "Unexpected and unplanned event" , "Unforeseen mishap" .)
