Cricket skipper Joe also right back (4)
I believe the answer is:
root
'cricket skipper joe' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'also right back' is the wordplay.
'also' becomes 'too' (synonyms).
'right' becomes 'r' (common abbreviation).
'back' says the letters should be written backwards.
'too'+'r'='toor'
'toor' backwards is 'ROOT'.
Can you help me to learn more?
(Other definitions for root that I've seen before include "burrow" , "Rhizome" , "support" , "Turn up with the snout." , "Rummage for plant base" .)
