Peers around rough entrances crossed by golfer (5)
I believe the answer is:
earls
'peers' is the definition.
(I know this)
'around rough entrances crossed by golfer' is the wordplay.
'entrances' says to take the initial letters (the entrances to the words).
'crossed by' indicates putting letters inside (inserted letters are crossed or covered by others).
'golfer' becomes 'Els' (Ernie Els - former number one professional golfer).
The initial letters of 'around rough' is 'ar'.
'ar' put inside 'els' is 'EARLS'.
(Other definitions for earls that I've seen before include "Nobles" , "members of the House of Lords" , "Lear's out for the flight of the nobility" , "Peers of the realm" , "They're below marquess and above viscount" .)
