Celebrities, for example, restricted by loans (7)
I believe the answer is:
legends
'celebrities' is the definition.
'example restricted by loans' is the wordplay.
'example' becomes 'eg'.
'restricted by' means one lot of letters goes inside another (I've seen this in other clues).
'loans' becomes 'lends' ('lend' can be a synonym of 'loan').
'eg' inserted into 'lends' is 'LEGENDS'.
'for' acts as a link.
(Other definitions for legends that I've seen before include "Stories handed down from the past" , "People admired" , "Old tales" , "The saintly lives" , "eg St George and the Dragon" .)
