Ivy leaves strewn around, offering little explanation (9)
I believe the answer is:
evasively
'around offering little explanation' is the definition.
I can't tell whether this definition defines the answer.
'ivy leaves strewn' is the wordplay.
'strewn' is an anagram indicator.
'ivy'+'leaves'='ivyleaves'
'ivyleaves' with letters rearranged gives 'EVASIVELY'.
Can you help me to learn more?
(Other definitions for evasively that I've seen before include "So as to avoid the point" , "In a devious manner" .)
