What's your point? Do you like it, hate it or are you neutral to it? Should there not HAVE been arguments over words or should there have been more? Your post could be expanded in so many ways, I hate when people just write something shallow and leave without actually making a point or giving us their opinion on the matter. Don't just make US do work, do some work yourself.
Reservation-thing wasn't about the word, it was about the rental firm's wrongful ACTIONS, and their flimsy rationalization. Furthermore, they didn't argue over what reservation means as you imply, but they argued about WHY they have reservations. This one is a failure on your part.
You forgot the 'Grace' thing, if you want to include the 'Coincidence' thing.
The 'Coincidence' thing is as much an argument about a word as 'Rava' is an actual finnish name.
I mean, it's about whether a coincidence has degrees or not - it's not really an argument about the word itself.
The 'Bet'-thing is NOT an argument over a word, it's an argument about whether a bet was actually made or not, and whether Kramer has an obligation to pay or not - it's just Kramer trying to weasel out of a situation, it's not an actual argument over a word at all.
The 'Wagon'-thing is based on an idiom that describes an alcoholic, and it's just people either misremembering the whole thing and its meaning or not, and trying to rationalize it afterwards by re-defining it by flimsy logic so they wouldn't be wrong. There's only one truth to this, and they don't really argue over a WORD anyway, it's the whole 'falling off the wagon'-thing, and it has multiple word sin it.
Meal can be defined in many ways, but from a quick research:
" The food served and eaten in one sitting.
A customary time or occasion of eating food.
The edible whole or coarsely ground grains of a cereal grass."
I don't think that leaves much room for interpretation. When they talk about 'three square meals a day' (I don't get why the shape of the meal is so important, round meal can be just as well-rounded), I think soup counts.
I think the confusion comes from the word meaning so many things, it can mean 'occasion of eating food' (Jerry's interpretation of 'act of sitting together and eating'), or it can mean just 'food'. I don't know why Americans wouldn't consider 'soup' real food for some reason, but in my opinion, it is.
