Clumsy golf shot, it provides play illuminators (10)
I believe the answer is:
footlights
'play illuminators' is the definition.
I can't tell whether this definition defines the answer.
'clumsy golf shot it' is the wordplay.
'clumsy' indicates an anagram.
'golf'+'shot'+'it'='golfshotit'
'golfshotit' anagrammed gives 'FOOTLIGHTS'.
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for footlights that I've seen before include "Theatrical profession" , "Theatre" , "Sources of illumination at front of stage" .)
