Not well versed about essential part of procedure, shows warrant (7)
I believe the answer is:
deserve
'warrant' is the definition.
(I've seen this before)
'not well versed about essential part of procedure' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'versed' is 'deserv' which is within the answer.
A single letter 'e' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
'shows' is the link.
Can you help me to learn more?
(Other definitions for deserve that I've seen before include "Severed (anag)" , "rate" , "Be worth" , "Justify" , "Merit, earn" .)
