Forbid daughter saying something cutting (7)
I believe the answer is:
bandsaw
'something cutting' is the definition.
I can't tell whether this defines the answer.
'forbid daughter saying' is the wordplay.
'forbid' becomes 'ban' (banning is a kind of forbiding).
'daughter' becomes 'd' (genealogical abbreviation).
'saying' becomes 'saw' (saw is a kind of saying).
'ban'+'d'+'saw'='BANDSAW'
Can you help me to learn more?
(Other definitions for bandsaw that I've seen before include "Powerful tool" , "Tool used by a carpenter or joiner" , "cutter" , "one might cut deal" .)
