Elevate nurse, 50, hampered by broken bone (7)
I believe the answer is:
ennoble
'elevate' is the definition.
(I know that ennoble is a more specific form of elevate)
'nurse 50 hampered by broken bone' is the wordplay.
'nurse' becomes 'EN' (abbreviation for state-enrolled nurse).
'50' becomes 'l' (Roman numeral).
'hampered by' is an insertion indicator.
'broken' indicates an anagram.
'bone' with letters rearranged gives 'nobe'.
'l' placed inside 'nobe' is 'noble'.
'en'+'noble'='ENNOBLE'
(Other definitions for ennoble that I've seen before include "Elevate to the aristocracy" , "Elevate in rank" , "Elevate; honour" , "Distinguish" , "Bestow peerage on" .)
