Stirrer stirring in tea leaves originally from the ground (11)
I believe the answer is:
terrestrial
'ground' is the definition.
Both the definition and answer are adjectives. Perhaps there's an association between them I don't understand?
'stirrer stirring in tea leaves originally' is the wordplay.
'stirring' indicates an anagram.
'in' means one lot of letters goes inside another.
'originally' indicates taking the first letters.
The initial letter of 'leaves' is 'l'.
'stirrer' with letters rearranged gives 'rrestri'.
'rrestri' put into 'tea' is 'terrestria'.
'terrestria'+'l'='TERRESTRIAL'
'from the' is the link.
Can you help me to learn more?
(Other definitions for terrestrial that I've seen before include "Relating to the earth" , "Relating to dry land" , "Land-based" , "Living on the ground" , "Not aquatic, arboreal, or aerial" .)
