A turn performed by a man, as you'd expect (7)
I believe the answer is:
'you'd expect' is the definition.
I can't tell whether this definition defines the answer.
'a turn performed by a man' is the wordplay.
'performed' indicates an anagram.
'by' says to put letters next to each other.
'a man' becomes 'al' ().
'aturn' is an anagram of 'natur'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for natural that I've seen before include "Simpleton", "chemical-free", "one short of being sharp?", "Not man-made; off-white", "person regarded as certain to qualify".)
