Couple linked perhaps to Romeo and Mina by river in the morning
I believe the answer is:
arm-in-arm
'couple linked perhaps' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'romeo and mina by river in the morning' is the wordplay.
'romeo' becomes 'r' (phonetic alphabet: alpha, bravo, charlie etc.).
'and' says to put letters next to each other.
'by river' becomes 'r' (I am not sure about the 'by' bit.**).
'in the' indicates putting letters inside.
'morning' becomes 'am'.
'r'+'mina'+'r'='rminar'
'rminar' placed into 'am' is 'ARM-IN-ARM'.
'to' is the link.
Can you help me to learn more?
(Other definitions for arm-in-arm that I've seen before include "Closely linked" , "With upper limbs linked in companionship" , "Linked at the elbows" , "Closely interlinked" , "Aggressive male" .)
