Local greeting of the Spanish; a shout heard in the Alps, perhaps? (5)
I believe the answer is:
yodel
'a shout heard in the alps perhaps?' is the definition.
I can't tell whether this definition defines the answer.
'local greeting of the spanish' is the wordplay.
'local greeting of' becomes 'yod' (I can't justify this - if you can you should give a lot more credence to this answer).
'the spanish' becomes 'el' ('the' in Spanish).
'yod'+'el'='YODEL'
Can you help me to learn more?
(Other definitions for yodel that I've seen before include "Sing in traditional Swiss manner" , "Sing partly falsetto" , "Swiss warble" , "Sing in intermittent falsetto" , "Sing in Tyrolean fashion" .)
