Enliven Spanish port cutting current charge (10)
I believe the answer is:
invigorate
'enliven' is the definition.
(synonyms)
'spanish port cutting current charge' is the wordplay.
'spanish port' becomes 'Vigo' (port in Spain).
'cutting' means one lot of letters goes inside another (some letters cut their way into a word).
'current' becomes 'in' ('in' can mean current or trendy).
'charge' becomes 'rate' (rate is a kind of charge).
'in'+'rate'='inrate'
'vigo' going into 'inrate' is 'INVIGORATE'.
(Other definitions for invigorate that I've seen before include "Give energy to" , "Strengthen" , "Liven up" , "Perk up" , "Give strength to" .)
