Father Christmas following echo somewhere in New Mexico (5,2)
I believe the answer is:
santa fe
'in new mexico' is the definition.
('Santa Fe' is part of 'new mexico')
'father christmas following echo somewhere' is the wordplay.
'father christmas' becomes 'Santa' (Santa Claus).
'following' becomes 'f' (used when citing page numbers etc).
'echo somewhere' becomes 'e' (phonetic alphabet: alpha, bravo, charlie etc.. I am not sure about the 'somewhere' bit.).
'santa'+'f'+'e'='SANTA FE'
Can you help me to learn more?
(Other definitions for santa fe that I've seen before include "Capital of New Mexico state" , "Capital city of New Mexico" , "US city" , "US state capital" .)
