He can vote for a noted lecturer or reader (7)
I believe the answer is:
elector
'he' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'vote for a noted lecturer or reader' is the wordplay.
I cannot really understand how this works, but
'vote' could be 'elect' and 'elect' is found within the answer.
'or' is within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'can' acts as a link.
Can you help me to learn more?
(Other definitions for elector that I've seen before include "Voter - old German prince" , "Citizen with a right to vote" , "Old Saxony, Hanover ruler" , "One eligible to vote" , "Crosses" .)
