Ordering lap dances, church folk start to tremble (9)
I believe the answer is:
placement
'ordering' is the definition.
(thesaurus)
'lap dances church folk start to tremble' is the wordplay.
'dances' indicates anagramming the letters.
'church' becomes 'ce' (Church of England).
'folk' becomes 'men' (both can mean people).
'start to' indicates taking the first letters.
The initial letter of 'tremble' is 't'.
'lap' with letters rearranged gives 'pla'.
'pla'+'ce'+'men'+'t'='PLACEMENT'
(Other definitions for placement that I've seen before include "Temporary posting" , "location" , "Arrangement" , "seating for dinner" , "Temporary job for work experience" .)
