Algerian port accommodating golf magazine (5)
I believe the answer is:
organ
'magazine' is the definition.
(I've seen this before)
'algerian port accommodating golf' is the wordplay.
'algerian port' becomes 'oran' (I've seen this before).
'accommodating' is an insertion indicator.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'oran' going around 'g' is 'ORGAN'.
(Other definitions for organ that I've seen before include "Newspaper; instrument" , "Ear, perhaps" , "Word after "pipe" or "barrel"" , "music producer" , "Agency" .)
