Time in South Africa - new different form of South Africa - marked in verse (6)
I believe the answer is:
stanza
'marked in verse' is the definition.
'stanza' can be an answer for 'verse' (a stanza is a verse of a poem). I'm not sure about the 'marked in' bit.
'time in south africa new different form of south africa' is the wordplay.
'time' becomes 't' (abbreviation).
'in' indicates putting letters inside.
'south africa' becomes 'SA' (abbreviation).
'new different form of' becomes 'n' (I am not sure about this - if you are sure you should believe this answer much more).
'south africa' becomes 'za' (abbreviation for Zuid-Afrika).
't' put inside 'sa' is 'sta'.
'sta'+'n'+'za'='STANZA'
Can you help me to learn more?
(Other definitions for stanza that I've seen before include "Part of a poem" , "Unit of a poem" , "piece by poet" , "Component of poem" , "piece of poetry" .)
