Flicker of an electric light? (6)
I believe the answer is:
switch
This might be a double definition.
'flicker' is the first definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'an electric light?' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'of' acts as a link.
Can you help me to learn more?
(Other definitions for switch that I've seen before include "Change, substitute" , "Contact breaker; change" , "Exchange; contactor" , "Change; false hair" , "Circuit-breaker" .)
