Make a copy, or have offspring (9)
I believe the answer is:
reproduce
I believe this is a triple definition!
'make' is the first definition.
(reproducing is a kind of making)
'a copy' is the second definition.
(I've seen this before)
'or' acts as a link.
'have offspring' is the third definition.
(I've seen this before)
(Other definitions for reproduce that I've seen before include "Duplicate" , "Procedure (anag.)" , "Create offspring" , "achieve propagation" , "Make a copy of (something)" .)
