Lift elbow to highest point (4)
I believe the answer is:
tope
'lift elbow' is the definition.
Although both the answer and definition are verbs in their base form, I can't see how they can define each other.
'highest point' is the wordplay.
'highest' becomes 'top' (I've seen this before).
'point' becomes 'e' (compass point).
'top'+'e'='TOPE'
'to' is the link.
Can you help me to learn more?
(Other definitions for tope that I've seen before include "plantation?" , "Drink a lot like poet" , "Drink to excess" , "What habitual drinkers do" , "Drink heavily" .)
