Way of working crank that has blokes entering tomb? (8)
I believe the answer is:
monument
'tomb?' is the definition.
(I know that monument is a type of sepulcher)
'way of working crank that has blokes entering' is the wordplay.
'way of working' becomes 'mo' (abbreviation for modus operandi).
'crank' becomes 'nut' (synonyms).
'that has' says to put letters next to each other.
'blokes' becomes 'men' (bloke can informally mean a man).
'entering' indicates putting letters inside.
'mo'+'nut'='monut'
'monut' enclosing 'men' is 'MONUMENT'.
(Other definitions for monument that I've seen before include "Lasting record" , "Memorial structure" , "London tube station" , "Commemorative structure" , "Commemorative column etc" .)
