State of coalminer working around bottom of mine (10)
I believe the answer is:
ceremonial
'state' is the definition.
(thesaurus)
'coalminer working around bottom of mine' is the wordplay.
'working' is an anagram indicator.
'around' means one lot of letters goes inside another.
'bottom of' suggests the final letters.
The last letter of 'mine' is 'e'.
'coalminer' with letters rearranged gives 'cremonial'.
'cremonial' enclosing 'e' is 'CEREMONIAL'.
'of' acts as a link.
(Other definitions for ceremonial that I've seen before include "Ritual procedure" , "Official" , "Ritual(istic)" , "Purely formal" .)
