A sheep circling around for something to drink (9)
I believe the answer is:
americano
'to drink' is the definition.
(type of coffee drink)
'a sheep circling around' is the wordplay.
'sheep' becomes 'merino' (breed of sheep).
'circling' is an insertion indicator (circling can mean going around or containing).
'around' becomes 'ca' (circa).
'merino' going around 'ca' is 'mericano'.
'a'+'mericano'='AMERICANO'
'for something' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for americano that I've seen before include "Espresso diluted with hot water" , "drink" , "Style of coffee" .)
