A couple of lines with Large Earl in motor and things are ok! (3,5)
I believe the answer is:
all clear
'ok' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'a couple of lines with large earl in motor and things' is the wordplay.
I cannot quite see how this works, but
'a' is present in the answer.
'lines' could be 'll' (I've seen this in other clues) and 'll' is present in the answer.
'large' could be 'l' and 'l' is found within the answer.
'earl' could be 'e' and 'e' is found within the answer.
'motor' could be 'car' (I've seen this before) and 'car' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'are' is the link.
Can you help me to learn more?
(Other definitions for all clear that I've seen before include "Signal to resume normal activities" , "I understand everything" , "Understood" , "no further questions needed" , "Siren sound to signal end of air raid" .)
