Show that one has a horn to turn to? (4)
I believe the answer is:
toot
'show that one has a horn' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's a link between them I don't understand?
'to turn to?' is the wordplay.
'turn' says the letters should be written backwards.
'to' written backwards gives 'ot'.
'to'+'ot'='TOOT'
Can you help me to learn more?
(Other definitions for toot that I've seen before include "Parp" , "Sound of a car horn" , "Horn's sound (T, not H)" , "Do it on a flute" , "Short sounding of horn" .)
