Itemised in every particular and maybe with the end clipped (8)
I believe the answer is:
detailed
'itemised' is the definition.
(thesaurus)
'with the end clipped' is the wordplay.
'with' says to put letters next to each other.
'the' becomes 'definite article' ('the' is the definite article in English).
'end' says to hollow out the word (remove centre letters) (I've seen 'ends' mean this).
'clipped' becomes 'tailed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'definitearticle' with its centre taken out is 'de'.
'de' put next to 'tailed' is 'DETAILED'.
'in every particular and maybe' acts as a link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for detailed that I've seen before include "supplying full particulars" , "Exhaustive" , "Meticulous" , "Elaborate" , "Showing even small features" .)
