Distribute a toll, or issue shares (5)
I believe the answer is:
allot
'issue shares' is the definition.
'allot' can be an answer for 'issue' (thesaurus). I'm not certain of the 'shares' bit.
'distribute a toll' is the wordplay.
'distribute' indicates anagramming the letters (I've seen this in other clues).
'a'+'toll'='atoll'
'atoll' anagrammed gives 'ALLOT'.
'or' is the link.
Can you help me to learn more?
(Other definitions for allot that I've seen before include "Distribute, give as share" , "Assign (to someone)" , "Ration" , "deal" , "Designate; sounds like much" .)
