Fraud gets involved in fifteenth-century exploratory mission (14)
I believe the answer is:
reconnaissance
'mission' is the definition.
(thesaurus)
'fraud gets involved in fifteenth-century exploratory' is the wordplay.
I cannot really understand how this works, but
'fraud' could be 'con' (con is a kind of fraud) and 'con' is located in the answer.
'gets' could be 'is' (I've seen this in other clues) and 'is' is found in the answer.
'century' could be 'c' (common abbreviation) and 'c' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for reconnaissance that I've seen before include "Initial survey" , "Preliminary survey" , "Scouting" , "Military observation" .)
