I was watching Better Call Saul the other night (Season 5, Episode 9, to be precise), and the character Kim Wexler exclaimed to Lalo Salamanca: “That‘s what you’re on about?”
I covered the expression “to be on about” something in 2013; it’s kind of the British equivalent to the American “going on and on about.” The problem with Kim’s use of it is that Better Call Saul is a prequel to Breaking Bad, with the current season taking place in 2004, and “on about” didn’t really take hold on these shores till after that. This chart from Google Ngrams Viewer gives a bit of a sense of the timeline:
I say “a bit” because both the British and American timelines overstate the use of the phrase, as a result of examples like a record review saying of a musician, “he’s on a lot about ten of the tracks.” My conclusion is that the NOOB “on about” was close to nonexistent in the U.S. in 2004, and would not have been used by a New Mexico lawyer with no apparent obsession with English television or novels.
At about the same time, I was talking with a University of Delaware colleague, Ann Manser, who said she was watching an actual English TV show, Lovejoy (Season 1, episode 9, “Death and [sic] Venice”), and was taken aback to hear an American character say “catch him up.”
That actually took me aback because I wasn’t familiar with the expression, which, Ann explained, is the equivalent of our “catch up to him.” (We do have a “catch [someone] up,” but it’s different. If a kid has missed school, the teacher might ask another student to “catch her up on what she missed.”) Ann said she and her husband thought the phrase was some sort of clue, maybe that the supposed American wasn’t really American after all. But no, there was no follow-up. You might call it, “The Case of the Shoddy Teleplay.”
