Twist formal legal document for recorder, maybe (4,10)
I believe the answer is:
wind instrument
'recorder maybe' is the definition.
(I know that fipple flute is a type of pipe)
'twist formal legal document' is the wordplay.
I cannot quite see how this works, but
'twist' could be 'wind' (synonyms) and 'wind' is found within the answer.
'document' could be 'instrument' (instrument is a kind of document) and 'instrument' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'for' acts as a link.
Can you help me to learn more?
(Other definitions for wind instrument that I've seen before include "Serpent for instance" , "Bit of brass" , "flute, perhaps" , "thing to have in orchestra" , "oboe, say" .)
