Smart visionary welcoming new tricks (9)
I believe the answer is:
chicanery
'tricks' is the definition.
(I have seen 'legal tricks' mean 'chicanery' so perhaps 'tricks' could also mean 'chicanery')
'smart visionary welcoming new' is the wordplay.
'smart' becomes 'chic' (both can mean stylish).
'visionary' becomes 'aery' (I can't justify this - if you can you should believe this answer much more).
'welcoming' indicates putting letters inside (in sense of 'inviting in').
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'aery' going around 'n' is 'anery'.
'chic'+'anery'='CHICANERY'
Can you help me to learn more?
(Other definitions for chicanery that I've seen before include "dishonest practices" , "jiggery-pokery" , "deceptive" , "Double-dealing" , "cheating" .)
