Thanks to Milan's strange charm (8)
I believe the answer is:
talisman
'charm' is the definition.
(I know that talisman is a type of charm)
'thanks to milan's strange' is the wordplay.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'strange' indicates anagramming the letters.
'milans' anagrammed gives 'lisman'.
'ta'+'lisman'='TALISMAN'
(Other definitions for talisman that I've seen before include "Protective charm" , "Object supposed to bring good luck" , "Object thought to guard against evil" , "Magical good luck charm" , "bringer of luck?" .)
