Has Colin become a saint for Christmas? (8)
I believe the answer is:
nicholas
'a saint for christmas?' is the definition.
I can't tell whether this defines the answer.
'has colin become' is the wordplay.
'become' indicates an anagram.
'has'+'colin'='hascolin'
'hascolin' is an anagram of 'NICHOLAS'.
Can you help me to learn more?
(Other definitions for nicholas that I've seen before include "Patron saint of children and Russia" , "Boy" , "For man" , "Russia's last emperor ..." , "Man's name; last tsar" .)
