Fifty for example will provide support (3)
I believe the answer is:
leg
'support' is the definition.
(I know that leg is a type of support)
'fifty for example' is the wordplay.
'fifty' becomes 'l' (Roman numeral).
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'l'+'eg'='LEG'
'will provide' is the link.
(Other definitions for leg that I've seen before include "Poultry portion" , "Run < on" , "Support; cricket side" , "Gigot" , "part of course" .)
