Lacking a real foundation? (8)
I believe the answer is:
mythical
'lacking a real foundation?' is the definition.
I can't judge whether this defines the answer.
'lacking a real foundation?' is the wordplay.
'lacking' becomes 'mythic' (I can't explain this - if you can you should believe this answer much more).
'foundation?' suggests the final letters (the letter at the bottom of the word).
The last letter of 'real' is 'l'.
'mythic'+'a'+'l'='MYTHICAL'
Can you help me to learn more?
(Other definitions for mythical that I've seen before include "Based on traditional stories" , "Existing in legends or traditional stories" , "Legendary" , "Imaginary or based on folk tales" , "Based on fable" .)
