An abbreviated moniker (3)
I believe the answer is:
ike
'an abbreviated moniker' is the definition.
The definition suggests a singular noun which matches the answer.
'an abbreviated moniker' is the wordplay.
'IKE' is hidden within the letters.
However, I am unsure how the hidden word is indicated.
Can you help me to learn more?
(Other definitions for ike that I've seen before include "President Eisenhower" , "Former US President (informally)" , "Nickname of old US president" , "Thirty fourth US president's nickname" , "Nickname for Dwight Eisenhower" .)
