Road sign shows absence of good round ruler (2,7)
I believe the answer is:
no parking
'road sign' is the definition.
(I've seen this in another clue)
'absence of good round ruler' is the wordplay.
'absence of' becomes 'no'.
'good round ruler' becomes 'parking' (I can't justify this - if you can you should give a lot more credence to this answer).
'no'+'parking'='NO PARKING'
'shows' acts as a link.
Can you help me to learn more?
(Another definition for no parking that I've seen is " not a welcoming sign".)
I've seen this clue in the Sydney Morning Herald.
Want a hint initially instead of a full solution?
