Notice learner receiving star presented by officer (7)
I believe the answer is:
admiral
'officer' is the definition.
(admiral is a kind of officer)
'notice learner receiving star' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'receiving' is an insertion indicator.
'star' becomes 'Mira' (star in the constellation Cetus).
'ad'+'l'='adl'
'adl' placed around 'mira' is 'ADMIRAL'.
'presented by' is the link.
(Other definitions for admiral that I've seen before include "Chief commander of fleet" , "Navy chief" , "Red butterfly in charge of the fleet" , "Commander of the fleet or butterfly" , "Senior officer; mad liar (anag.)" .)
