Water I consumed in rising church centre (5)
I believe the answer is:
evian
'water' is the definition.
(mineral water brand)
'i consumed in rising church centre' is the wordplay.
'i consumed in' becomes 'ive' (I can't justify this - if you can you should give a lot more credence to this answer).
'rising' shows that the letters should be reversed in order (going up in a down clue).
'church' becomes 'fane'.
'centre' indicates the central letters.
The middle letters of 'fane' are 'an'.
'ive' reversed gives 'evi'.
'evi'+'an'='EVIAN'
Can you help me to learn more?
(Other definitions for evian that I've seen before include "spa town" , "This water" , "springwater" .)
