Gratuities dry up where turds gather? (7)
I believe the answer is:
cesspit
'turds gather?' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'gratuities dry up' is the wordplay.
'gratuities' becomes 'tips' ('tip' can be a synonym of 'gratuity').
'dry' becomes 'sec' ('dry' in French - used for wine).
'up' is a reversal indicator (in down clue: letters go upwards).
'tips'+'sec'='tipssec'
'tipssec' written backwards gives 'CESSPIT'.
'where' is the link.
Can you help me to learn more?
(Other definitions for cesspit that I've seen before include "Place for filthy water" , "Sewage holder" , "Foul and squalid place" , "means of waste disposal" , "Sewage storer" .)
