Row of books, one with green jacket (9)
I believe the answer is:
commotion
'row' is the definition.
(I've seen this before)
'books one with green jacket' is the wordplay.
I cannot quite understand how this works, but
'books' could be 'ot' (abbreviation for Old Testament) and 'ot' is present in the answer.
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'green' could be 'common' (synonyms) and 'common' is found within the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
'of' is the link.
Can you help me to learn more?
(Other definitions for commotion that I've seen before include "Row" , "Disorderly outburst" , "Rumpus" .)
