I say, are you writing up boring event with touchdown zone? (6)
I believe the answer is:
runway
'touchdown zone?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'i say are you writing up boring event' is the wordplay.
'i say are' becomes 'r' (I can't justify this - if you can you should give a lot more credence to this answer).
'you' becomes 'u' (homophones).
'writing up' is a reversal indicator.
'boring event' becomes 'yawn' (I've seen this before).
'yawn' backwards is 'nway'.
'r'+'u'+'nway'='RUNWAY'
'with' is the link.
Can you help me to learn more?
(Other definitions for runway that I've seen before include "Landing surface" , "Strip for take off and landing of aircraft" , "Airstrip" , "A plane takes off from it" , "A plane lands on it" .)
