Unstable gun woman's repressing urges (7)
I believe the answer is:
hungers
'repressing urges' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot see how they can define each other.
'unstable gun woman's' is the wordplay.
I cannot quite see how this works, but
an anagram of 'gun' is 'ung' which is located in the answer.
'woman's' could be 'hers' (her refers to a woman) and 'hers' is found in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hungers that I've seen before include "Craves food" , "Thirsts" .)
