Article on South African appearing in May? (7)
I believe the answer is:
theresa
'may?' is the definition.
(I've seen this before)
'article on south african' is the wordplay.
'article' becomes 'the' (the 'definite article' part of speech).
'on' becomes 're' ('on' can be mean 'with reference to').
'south african' becomes 'sa'.
'the'+'re'+'sa'='THERESA'
'appearing in' is the link.
(Other definitions for theresa that I've seen before include "May's one" , "Girl's name" , "Lisieux saint" , "Maria -, eighteenth century empress" , "Maria ___ , Archduchess of Austria, d. 1780" .)
