Did crow start to become dishevelled? (7)
I believe the answer is:
tangled
'dishevelled?' is the definition.
('tangle' can be a synonym of 'dishevel')
'did crow start' is the wordplay.
'did' becomes 'led' (leading is a kind of doing).
'crow' becomes 'tang' (I can't justify this - if you can you should believe this answer much more).
'start' says to put letters next to each other.
'led' put after 'tang' is 'TANGLED'.
'to become' is the link.
Can you help me to learn more?
(Other definitions for tangled that I've seen before include "Intertwined" , "''Oh what a ... web we weave / when first we practise to deceive'' (Walter Scott)" , "All twisted together" , "Caught" , "Twisted into confused mass" .)
