Second request for watering device? (7)
I believe the answer is:
sprayer
'watering device?' is the definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'second request' is the wordplay.
'second' becomes 's' (common abbreviation).
'request' becomes 'prayer' (prayer is a kind of request).
's'+'prayer'='SPRAYER'
'for' is the link.
Can you help me to learn more?
(Other definitions for sprayer that I've seen before include "Device to dispense liquid as a fine mist" , "Dispersing agent - aerosol" , "he'll paint your car" , "Atomiser" , "Sprinkler" .)
