Certainly needing pen to depict classic Western scene (2,6)
I believe the answer is:
ok corral
'depict classic western scene' is the definition.
I can't judge whether this definition defines the answer.
'certainly needing pen' is the wordplay.
'certainly' becomes 'OK' (both can mean 'yes').
'needing' means one lot of letters go next to another.
'pen' becomes 'corral' (both are a type of enclosure for animals).
'ok'+'corral'='OK CORRAL'
'to' is the link.
Can you help me to learn more?
(Other definitions for ok corral that I've seen before include "Tombstone feature" , "Scene of 16 in 19" , "Site of famous gunfight in Tombstone" , "shooting scene" .)
