Attachment for Sam, say, that's vital for Twist -- and Pip, evidently? (9)
I believe the answer is:
standpipe
'attachment' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'sam say that's vital for twist and pip evidently?' is the wordplay.
'STANDPIPE' is hidden within the letters.
However, I'm uncertain how this is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for standpipe that I've seen before include "Emergency water supply" , "Temporary water outlet" , "main conduit in emergencies?" , "Source of water during shortage" , "temporary feed" .)
