Always seen in Monteverde (4)
I believe the answer is:
ever
'always' is the definition.
(synonyms)
'in monteverde' is the wordplay.
'in' indicates a hidden word.
'EVER' can be found hidden inside 'monteverde'.
'seen' is the link.
(Other definitions for ever that I've seen before include "Continuously" , "Possibly" , "Continually" , "Eternity" , "At all times, always" .)
