Name first words of 'Somewhere' (7)
I believe the answer is:
theresa
'words of somewhere' is the definition.
I can't tell whether this definition defines the answer.
'name first' is the wordplay.
'name' becomes 'theres' (I am not sure about this - if you are sure you should believe this answer much more).
'first' becomes 'a'.
'theres'+'a'='THERESA'
(Other definitions for theresa that I've seen before include "Maria --, Austrian ruler" , "Maria ___ , Archduchess of Austria, d. 1780" , "Lisieux saint" , "Avila/Lisieux saints' name" , "May's one" .)
