Chaplain (5)
'chaplain' is the definition.
(I know that chaplain can be written as padre)
This is the entire clue.
(Other definitions for padre that I've seen before include "Chaplain to armed forces" , "Minister" , "Father" , "Services' chaplain" , "Priest, chaplain" .)
(Other definitions for serviceman that I've seen before include "car maintained by him?" , "Tommy" , "Member of the armed forces" , "Private" .)
