Quietly move to recommend book millions ignored (6)
I believe the answer is:
tiptoe
'quietly move to' is the definition.
I can't tell whether this definition defines the answer.
'recommend book millions ignored' is the wordplay.
'recommend' becomes 'tip'.
'book' becomes 'tome' (a tome is a book).
'millions' becomes 'm' (abbreviation).
'ignored' is a deletion indicator.
'tome' with 'm' taken away is 'toe'.
'tip'+'toe'='TIPTOE'
Can you help me to learn more?
(Other definitions for tiptoe that I've seen before include "''... through the tulips'' (Tiny Tim song)" , "Walk very quietly with heels raised" , "Walk very carefully" , "Creep" , "Keep quiet" .)
