Zulu minister needs to acquire spectacles to get a closer look (4,2)
I believe the answer is:
zoom in
'get a closer look' is the definition.
(I've seen this in another clue)
'zulu minister needs to acquire spectacles' is the wordplay.
'zulu' becomes 'Z' (phonetic alphabet: alpha, bravo, charlie etc.).
'minister needs' becomes 'min' (I've seen this in other clues. I am not sure about the 'needs' bit.).
'to acquire' indicates putting letters inside.
'spectacles' becomes 'oo' (I've seen this in other clues).
'z'+'min'='zmin'
'zmin' going around 'oo' is 'ZOOM IN'.
'to' is the link.
Can you help me to learn more?
(Another definition for zoom in that I've seen is " Focus more closely".)
