Texan possibly freaks out her nervous hosts (10)
I believe the answer is:
southerner
'texan' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'freaks out her nervous hosts' is the wordplay.
'hosts' indicates the answer is hidden within the clue.
'SOUTHERNER' can be found hidden inside 'freaks out her nervous'.
'possibly' is the link.
Can you help me to learn more?
(Other definitions for southerner that I've seen before include "Alabaman" , "One from lower down the country" .)
