Our sea trip is designed to enliven (6)
I believe the answer is:
arouse
'to enliven' is the definition.
(thesaurus)
'our sea trip' is the wordplay.
'trip' indicates an anagram.
'our'+'sea'='oursea'
'oursea' anagrammed gives 'AROUSE'.
'is designed' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for arouse that I've seen before include "Ginger up" , "Galvanize" , "Excite, awaken" , "Set off" , "Waken up or stimulate feeling" .)
