New electronic mobile home in Spain that helps me relax (7)
I believe the answer is:
nervine
'spain that helps me relax' is the definition.
The definition suggests a singular noun which matches the answer.
'new electronic mobile home in' is the wordplay.
'new' becomes 'n' (abbreviation as in New Testament NT).
'electronic' becomes 'e' (as in e-mail or e-books).
'mobile home' becomes 'ervin' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' indicates putting letters inside.
'n'+'e'='ne'
'ne' going around 'ervin' is 'NERVINE'.
Can you help me to learn more?
(Another definition for nervine that I've seen is " drug".)
