Very with it in Mediterranean country, so go (8)
I believe the answer is:
vitality
'go' is the definition.
(I've seen this before)
'very with it in mediterranean country' is the wordplay.
'very' becomes 'v' (abbreviation).
'with' says to put letters next to each other.
'in' is an insertion indicator.
'mediterranean country' becomes 'italy' (I've seen this before).
'it' placed within 'italy' is 'itality'.
'v'+'itality'='VITALITY'
'so' is the link.
(Other definitions for vitality that I've seen before include "go" , "Life force and animation" , "Liveliness" , "Vigour; ability to prosper" , "Vibrancy, energy" .)
