King's heading south-east to visit coastal town for brief inspection (4-3)
I believe the answer is:
look-see
'brief inspection' is the definition.
(I've seen this before)
'king's heading south-east to visit coastal town' is the wordplay.
'heading' indicates taking the first letters (head could mean the top letter).
'south east' becomes 'SE' (abbreviation).
'to visit' is an insertion indicator (inserted letters visit others).
'coastal town' becomes 'looe' (I have seen 'Cornish town ' mean 'looe' so perhaps 'town' could also mean 'looe'. I am not sure about the 'coastal' bit.).
The first letter of 'kings' is 'k'.
'k'+'se'='kse'
'kse' put into 'looe' is 'LOOK-SEE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for look-see that I've seen before include "Dekko" , "Inspection (colloq.)" , "Survey, inspection" , "Brief inspection" , "Young's - relates stress and strain (Physics)" .)
