Disorganised flight given the seal of approval by leading experts (8)
I believe the answer is:
stampede
'approval by leading experts' is the definition.
I can't tell whether this definition defines the answer.
'disorganised flight given the seal' is the wordplay.
'disorganised flight' becomes 'ede' (I can't explain this - if you can you should believe this answer much more).
'given' means one lot of letters go next to another.
'the seal' becomes 'stamp' (synonyms).
'ede' after 'stamp' is 'STAMPEDE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for stampede that I've seen before include "Chaotic rush" , "A flight of frightened cattle" , "Panicked rush (of cattle)" , "rush for safety maybe" , "Crazy pets made a sudden rush" .)
