One may get something from television that they couldn't get from radio (3,6)
I believe the answer is:
lip reader
'television that they couldn't get from radio' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'one may get something' is the wordplay.
'one may' becomes 'lipread' (I can't explain this - if you can you should believe this answer much more).
'get' is a charade indicator (letters next to each other).
'something' becomes 'er' (I've seen this in other clues).
'lipread'+'er'='LIP-READER'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for lip reader that I've seen before include "One compensating for deafness" , "may well be deaf?" , "Person interpreting from mouth movements" , "One, usually deaf, who uses sight to understand conversation" , "Interpreter of mouth movements" .)
