Pips in terrible tart made by monk (8)
I believe the answer is:
trappist
'monk' is the definition.
(member of the Trappist order of monks)
'pips in terrible tart' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'pips' is 'ppis' which is within the answer.
an anagram of 'tart' is 'trat' which is located in the left over letters.
No letters remain.
This explanation may well be incorrect...
'made by' acts as a link.
Can you help me to learn more?
(Other definitions for trappist that I've seen before include "Austere (and silent) monk" , "Past trip (anag.)" , "One of an austere and silent order" , "Monk vowed to silence" , "who likes to be silent?" .)
