Neglect to send out Times: they haven’t taken orders (5)
I believe the answer is:
laity
'they haven't taken orders' is the definition.
(ordinary people who haven't taken religious orders)
'neglect to send out times' is the wordplay.
'neglect' becomes 'laxity' (being lax is being neglectful).
'to send out' indicates named letters should be taken away.
'times' becomes 'x' (multiplication sign).
'laxity' with 'x' taken out is 'LAITY'.
(Other definitions for laity that I've seen before include "amateurs" , "Those not in holy orders" , "Non-clerics" , "part of church" , "Non-specialists" .)
