Ridiculous myths involving one place where metal is worked (6)
I believe the answer is:
smithy
'place where metal is worked' is the definition.
I can't judge whether this definition defines the answer.
'ridiculous myths involving one' is the wordplay.
'ridiculous' indicates anagramming the letters.
'involving' is an insertion indicator.
'one' becomes 'i' (Roman numeral).
'myths' is an anagram of 'smthy'.
'smthy' going around 'i' is 'SMITHY'.
Can you help me to learn more?
(Other definitions for smithy that I've seen before include "Workshop with anvil" , "work area" , "Blacksmith's workplace" , "Vulcan was concerned?" , "Where 3s were made and fitted" .)
