Spirited international very into beer (5)
I believe the answer is:
alive
'spirited' is the definition.
(full of life)
'international very into beer' is the wordplay.
'international' becomes 'i' (abbreviation eg in IMF).
'very' becomes 'v' (abbreviation).
'into' indicates putting letters inside.
'beer' becomes 'ale' (type of beer).
'i'+'v'='iv'
'iv' inserted within 'ale' is 'ALIVE'.
(Other definitions for alive that I've seen before include "In existence" , "Go or walk briskly" , "''Crying cockles and mussels, ..., ..., oh'' (Molly Malone)" , "answer, as it happens" , "full of vitality" .)
