Item I cloned for old… (3)
I believe the answer is:
two
'item' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for two that I've seen before include "prime -- that's not odd" , "Company allegedly" , "Fifth root of thirty-two" , "Pair, deuce" , "II" .)
