Punctually
'punctually' is the definition.
(eg 7 o'clock on the dot means 7 o'clock exactly)
This is the entire clue.
(Other definitions for on the dot that I've seen before include "Absolutely punctual" , "Precisely punctual" , "Prompt" , "At precisely the right time" , "Promptly" .)
'punctually' is the definition.
(eg 7 o'clock on the dot means 7 o'clock exactly)
This is all the clue.
