Share it with Nora perhaps (6)
I believe the answer is:
ration
'share' is the definition.
(a ration is a share of a limited resource)
'it with nora perhaps' is the wordplay.
'with' says to put letters next to each other.
'perhaps' is an anagram indicator.
'it' put after 'nora' is 'norait'.
'norait' anagrammed gives 'RATION'.
(Other definitions for ration that I've seen before include "Fixed restricted allowance" , "adequate amount" , "Quota" , "Restrict the supply of" , "Limited allocation of food etc in wartime" .)
