Aim east and deliver tea (9)
I believe the answer is:
orientate
'aim' is the definition.
Although both the answer and definition are verbs in their base form, I cannot see how they can define each other.
'east and deliver tea' is the wordplay.
I cannot quite understand how this works, but
'east' could be 'orient' (synonyms) and 'orient' is found in the answer.
an anagram of 'tea' is 'ate' which is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for orientate that I've seen before include "leave the West implicitly?" , "Become accustomed to new situation" , "Get bearings, become accustomed to situation" , "Give direction to" , "Adjust" .)
