Boy from the Ministry? (3)
I believe the answer is:
mod
'ministry?' is the definition.
(Ministry of Defence)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for mod that I've seen before include "Rocker's rival?" , "1960s teenager" , "ministry" , "Gaelic literary festival" , "Meeting of the Scottish" .)
