An alphabetical list is on hand (5)
I believe the answer is:
index
I believe this is a double definition.
'an alphabetical list' is the first definition.
(I've seen this before)
'on hand' is the second definition.
(I know that index anatomical location hand)
'is' acts as a link.
(Other definitions for index that I've seen before include "Forefinger" , "A-to-Z listing" , "Pointer" , "Reference" , "List at end of book" .)
