On time to help erring actor? (6)
I believe the answer is:
prompt
This could be a double definition.
'on time' is the first definition.
(synonyms)
'help erring actor?' is the second definition.
'prompt' can be an answer for 'help' (thesaurus). I am unsure of the 'erring actor?' bit.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for prompt that I've seen before include "Punctual or timely" , "keeping to the right time" , "Immediate - supply actor's lines" , "Refresh the memory -- on time" , "effective in expedition" .)
