Just recently I was in a conversation with a number of UK mainlanders and we had a debate over what “tories” meant, apparently disproportionately ordinarily it refers to a political party and it’s not usual to use it as short for “territories” as I’ve used it (according to how the debate ended, it was half and half between them). And once again I’m reminded of how people feel to look back at their usage of a word/phrase over the years and cringe.
More tragically, me and a friend were embarrassed once upon realizing everyone was confusing “encephalitis” with “hydrocephalus” when talking to someone about their kid with hydrocephalus. Awkward because encephalitis is caused by HIV.
Just because it has been brought to the table doesn’t mean it will go anywhere else. “Tabling” a discussion suggests that we are stepping away from the table for now. We are taking away any deal we have struck, but leaving behind any issue still under contention. Maybe we will bring it up when we come back, maybe not.
We use “tabling” in much the same sense as the idiom “leaving money on the table”, meaning “concluding a transaction without demanding all consideration owed to you”.
Then it is shelved. Basically for a later dated. Tabled is where the discussions take place.
