Stretch of land that’s been cleared shows error (8)
I believe the answer is:
airstrip
'stretch of land that's been cleared' is the definition.
I can't judge whether this defines the answer.
'shows error' is the wordplay.
'shows' becomes 'airs' (shows on TV).
'error' becomes 'trip' (trip is a kind of error).
'airs'+'trip'='AIRSTRIP'
Can you help me to learn more?
(Other definitions for airstrip that I've seen before include "essential to a Kennedy" , "Land here" , "Rough landing area" , "Temporary runway" , "possible starting place" .)
