Enthuse over the new door at the end of the hall (5)
I believe the answer is:
drool
'enthuse' is the definition.
Although both the answer and definition are verbs in their base form, I don't understand how they can define each other.
'the new door at the end of the hall' is the wordplay.
'the new' indicates an anagram.
'at the end of' indicates one should take the final letters.
The last letter of 'hall' is 'l'.
'door' is an anagram of 'droo'.
'droo'+'l'='DROOL'
'over' acts as a link.
Can you help me to learn more?
(Other definitions for drool that I've seen before include "Slaver - drivel" , "Salivate" , "dribble" , "Dogs may" , "Let saliva run from the mouth" .)
