jwjarvis commented on the word onset
The outset is when something starts fully formed: This project was doomed from the outset....I promised myself I would work hard from the very outset.
Onset is something forming: The onset of the disease is slow and painful....I fear the onset of war....The war will be vicious from the outset.
In terms of usage, it seems onset can be subject or object, whereas outset is always (or at least commonly) prepositional 'from the outset', 'at the outset'.
