Having the following sentence: "One drunken punch-up too many saw him meet his maker", could you please explain to me what is what in this sentence(object, subject etc.)? Because while I get the overall meaning of the sentence I don't get how it is constructed. Especially I don't understand what "too many" is doing there.
One drunken punch-up too many saw him meet his maker
The main verb in this sentence is see in this context it means to be the time or place when something happens. The link provides an example showing how it can be used in this way, with something (not a person) seeing an event.
The subject is one drunken punch-up too many. This suggests that this person regularly gets into fights when drunk, and this particular fight was one too many.
This expression is normally used about alcohol: the implication is that if you drink a sensible amount, everything is fine, but one too many results in a hangover, bad behaviour, etc.
We can see why it was one fight too many when we look at the object: it saw him meet his maker. This is an idiom meaning to die: literally it means to meet God, which is supposed to happen when you die.
