In the morning, colleague has radar as an example (7)
I believe the answer is:
acronym
'radar as an example' is the definition.
I can't tell whether this defines the answer.
'in the morning colleague' is the wordplay.
'in the' indicates putting letters inside.
'morning' becomes 'am' (as in 12:00 AM).
'colleague' becomes 'crony' (crony can mean a colleague or associate).
'am' placed around 'crony' is 'ACRONYM'.
'has' is the link.
Can you help me to learn more?
(Other definitions for acronym that I've seen before include "UNESCO, say" , "quango, perhaps" , "Nimby is one" , "NATO, for example" , "FBI?" .)
