Give out to young woman losing the head up north around summit of Gullion (6)
I believe the answer is:
assign
'give out' is the definition.
(I've seen this in another clue)
'up north around summit of gullion' is the wordplay.
'up' is a reversal indicator (in down clue: letters go upwards).
'north' becomes 'nissa' (I can't justify this - if you can you should give a lot more credence to this answer).
'around' means one lot of letters goes inside another.
'summit of' suggests taking the first letters.
The initial letter of 'gullion' is 'g'.
'nissa' enclosing 'g' is 'ngissa'.
'ngissa' backwards is 'ASSIGN'.
'to young woman losing the head' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for assign that I've seen before include "Appoint or ascribe." , "Allocate; designate" , "Allocate (a task or duty)" , "Allocate (duties to someone)" , "Allocate, a job say" .)
