Extremes of risk entertained by female labourer (7)
I believe the answer is:
workman
'labourer' is the definition.
(I've seen this before)
'extremes of risk entertained by female' is the wordplay.
'extremes of' suggests removing the centre.
'entertained by' is an insertion indicator (I've seen this in other clues).
'female' becomes 'woman' (woman is a kind of female).
'risk' with its middle taken out is 'rk'.
'rk' inserted into 'woman' is 'WORKMAN'.
(Other definitions for workman that I've seen before include "Artisan" , "employee" , "Manual labourer" .)
