Turn each into something formless (8)
I believe the answer is:
inchoate
'formless' is the definition.
(thesaurus)
'turn each into' is the wordplay.
'turn' is an anagram indicator.
'each'+'into'='eachinto'
'eachinto' with letters rearranged gives 'INCHOATE'.
'something' is the link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for inchoate that I've seen before include "Action he took having just begun" , "Just begun, not yet fully developed" , "Confused" , "Immature" , "Undeveloped" .)
