Overseas character in a spot beginning to hunt for navigation angle (7)
I believe the answer is:
azimuth
'navigation angle' is the definition.
'azimuth' can be an answer for 'angle' (azimuth is a kind of angle). I'm not certain of the 'navigation' bit.
'overseas character in a spot beginning to hunt' is the wordplay.
'overseas character' becomes 'mu' (Greek letter. I am not sure about the 'overseas' bit.).
'in' is an insertion indicator.
'spot' becomes 'zit' (spot on one's body).
'beginning to' suggests taking the first letters.
The initial letter of 'hunt' is 'h'.
'a'+'zit'='azit'
'mu' going within 'azit' is 'azimut'.
'azimut'+'h'='AZIMUTH'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for azimuth that I've seen before include "Horiz. angle (of compass bearing)" , "Horizontal angle of a compass bearing" , "Astronomical angle --" , "heading for a star" , "(In astronomy and navigation) angle of a bearing measured clockwise from North" .)
