On and off (5)
(Other definitions for intermittently that I've seen before include "So as to occur at irregular intervals" , "Not all the time" , "sometimes" , "(Happening) with pauses now and then" .)
This might be a double definition.
'on' is the first definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'off' is the second definition.
(both can mean departing)
'and' acts as a link.
Can you help me to learn more?
(Other definitions for going that I've seen before include "attending" , "repeated as sale nears completion" , "Available" , "Surface condition (that may get tough!)" , "Moving away, departing" .)
