Live at home, outside evacuated regional capital (6)
I believe the answer is:
berlin
'capital' is the definition.
(Berlin is an example)
'live at home outside evacuated regional' is the wordplay.
'live' becomes 'be' ('be' can be a synonym of 'live'**).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'outside' indicates putting letters inside.
'evacuated' suggests removing the centre.
'regional' with its centre removed is 'rl'.
'be'+'in'='bein'
'bein' placed around 'rl' is 'BERLIN'.
(Other definitions for berlin that I've seen before include "A once-divided city" , "capital city" , "Composer of White Christmas" , "German capital" , "Irving -, Russian-born musical composer" .)
