Swear, as lovers, to be reunited to the end of time (7)
I believe the answer is:
resolve
'swear' is the definition.
The answer and definition can be both to do with communicating as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'lovers to be reunited to the end of time' is the wordplay.
'to be reunited' indicates an anagram (I've seen 'reuniting' mean this (letters are put together again in a new way)).
'to the end of' says to take the final letters.
The final letter of 'time' is 'e'.
'lovers' anagrammed gives 'resolv'.
'resolv'+'e'='RESOLVE'
'as' acts as a link.
Can you help me to learn more?
(Other definitions for resolve that I've seen before include "Firmly decide" , "Fix" , "Settle; determination" , "find an answer" , "Clear up: courage" .)
