One like Rudolph — check red round about tip of nose (8)
I believe the answer is:
reindeer
'one like rudolph' is the definition.
The definition suggests a singular noun which matches the answer.
'check red round about tip of nose' is the wordplay.
'check' becomes 'rein' (both can mean to control or limit).
'round' says the letters should be written backwards.
'about' means one lot of letters goes inside another.
'tip of' says to take the final letters.
The final letter of 'nose' is 'e'.
'red' back-to-front is 'der'.
'der' enclosing 'e' is 'deer'.
'rein'+'deer'='REINDEER'
Can you help me to learn more?
(Other definitions for reindeer that I've seen before include "Rudolph, for instance" , "Dancer, Prancer etc." , "They pull Santa's sleigh" , "Santa's sleigh pullers" , "Santa's sleigh puller" .)
