Snake discovered in Utah on top of sump by those formerly in the sink business? (6)
I believe the answer is:
uboats
'those formerly in the sink business?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'snake discovered in utah on top of sump' is the wordplay.
'snake' becomes 'boa' (boa is a kind of snake).
'discovered in' is an insertion indicator.
'utah' becomes 'ut' (I've seen this in other clues).
'on top of' says to take the initial letters.
The initial letter of 'sump' is 's'.
'boa' inserted into 'ut' is 'uboat'.
'uboat'+'s'='UBOATS'
'by' acts as a link.
Can you help me to learn more?
(Another definition for uboats that I've seen is " subs ...".)
