It's on the cards it may be sown (3)
I believe the answer is:
pip
'it may be sown' is the definition.
The definition suggests a singular noun which matches the answer.
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for pip that I've seen before include "Palindromic fruit seed" , "Great Expectations hero" , "one signals lieutenant" , "Philip" , "Narrowly beat" .)
