Speak at length about early sign of femoral rupture (9)
I believe the answer is:
perforate
'femoral rupture' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'speak at length about early sign' is the wordplay.
'speak at length' becomes 'perorate' (I've seen this before).
'about' is an insertion indicator.
'early sign' becomes 'f' (I can't justify this - if you can you should give a lot more credence to this answer).
'perorate' going around 'f' is 'PERFORATE'.
'of' is the link.
Can you help me to learn more?
(Other definitions for perforate that I've seen before include "bore!" , "Puncture" , "punch" , "Make hole or holes through" , "pass through hole" .)
