Staff regularly reading magazines (3)
I believe the answer is:
man
'staff' is the definition.
(as in staffing or manning a particular place)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for man that I've seen before include "Provide with crew" , "Chap" , "knight, perhaps?" , "Dude" , "Isle of ..., ... o'war" .)
