Fiancée regularly skipped introduction to fairy tale - beyond words! (9)
I believe the answer is:
ineffable
'beyond words' is the definition.
(I've seen this before)
'fiancee regularly skipped introduction to fairy tale' is the wordplay.
'regularly skipped' means one should take alternating letters.
'introduction to' says to take the initial letters (I've seen 'introductions to' mean this).
'tale' becomes 'fable' (I have seen 'Moral tale' mean 'fable' so perhaps 'tale' could also mean 'fable').
The initial letter of 'fairy' is 'f'.
The alternate letters of 'fiancee' are 'ine'.
'ine'+'f'+'fable'='INEFFABLE'
(Other definitions for ineffable that I've seen before include "Indescribable in words" , "Unutterable, too great to be described" , "Defying description" , "impossible to describe" , "Too sacred to be spoken" .)
