Elation: Juliet and Romeo, finally, finally together (3)
I believe the answer is:
joy
'elation' is the definition.
(I've seen this before)
'juliet and romeo finally finally together' is the wordplay.
'juliet' becomes 'J' (phonetic alphabet: alpha, bravo, charlie etc.).
'and' says to put letters next to each other.
'finally' indicates one should take the final letters.
'finally together' becomes 'y' (I can't explain this - if you can you should give a lot more credence to this answer).
The last letter of 'romeo' is 'o'.
'j'+'o'+'y'='JOY'
Can you help me to learn more?
(Other definitions for joy that I've seen before include "Rapture" , "Intense gladness" , "Great happiness" , "Delight" , "Elation" .)
