Spat out bathroom fittings (4)
I believe the answer is:
taps
'bathroom fittings' is the definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's an association between them I don't understand?
'spat out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'spat' is an anagram of 'TAPS'.
Can you help me to learn more?
(Other definitions for taps that I've seen before include "Flow controllers" , "The sound of lights out" , "They're faucets in America" , "Uses listening devices" , "Military signal to turn the lights out" .)
