Science on bone obtained unscrupulously and put down quickly (9)
I believe the answer is:
scribbled
'put down quickly' is the definition.
I can't tell whether this defines the answer.
'science on bone obtained unscrupulously' is the wordplay.
'science' becomes 'sc'.
'on' says to put letters next to each other.
'bone' becomes 'rib' (rib is a type of bone).
'obtained unscrupulously' becomes 'bled' (I can't explain this - if you can you should believe this answer much more).
'sc'+'rib'+'bled'='SCRIBBLED'
'and' is the link.
Can you help me to learn more?
(Other definitions for scribbled that I've seen before include "Written carelessly" , "Left hand's traces showing carelessness" , "Scrawled" .)
