Dangerous situation, being born during midlife crisis (9)
I believe the answer is:
minefield
'dangerous situation' is the definition.
(a minefield is a dangerous or perilous situation)
'born during midlife crisis' is the wordplay.
'born' becomes 'ne' ('born' in French - used to indicate a birth name).
'during' indicates putting letters inside.
'crisis' is an anagram indicator.
'midlife' with letters rearranged gives 'mifield'.
'ne' going into 'mifield' is 'MINEFIELD'.
'being' is the link.
(Other definitions for minefield that I've seen before include "Dangerous area" , "Sensitive area" , "Danger zone" , "Highly delicate situation (where one must watch one's step!)" .)
