Perfect films regularly shown around various parts of Wales (8)
I believe the answer is:
flawless
'perfect' is the definition.
(similar in meaning)
'around various parts of wales' is the wordplay.
'around' means one lot of letters goes inside another.
'various parts' becomes 'fls' (I am not sure about this - if you are sure you should believe this answer much more).
'of' indicates an anagram (the answer comes from or 'of' the letters).
'wales' anagrammed gives 'awles'.
'fls' enclosing 'awles' is 'FLAWLESS'.
'films regularly shown' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for flawless that I've seen before include "Perfect, without defect" , "Unblemished" , "sinner isn't this" , "Without blemish or fault" , "unimpaired" .)
