Give the sheep a bit of a scare as you run away (5)
I believe the answer is:
scram
'a bit of a scare as you run away' is the definition.
I can't judge whether this definition defines the answer.
'give the sheep' is the wordplay.
'give' becomes 'sc' (I can't justify this - if you can you should give a lot more credence to this answer).
'the sheep' becomes 'ram' (ram is a kind of sheep).
'sc'+'ram'='SCRAM'
Can you help me to learn more?
(Other definitions for scram that I've seen before include "Beat it, get lost, go away" , "Vamoose" , "In slang, go away and beat it" , "beat hasty retreat" , "Bolt" .)
