I was tweet-talking with Lane Greene this morning about whether Americans’ love for/Britons’ indifference to optional commas can be quantified. And so I did a little experiment. And so I’m going to tell you about it.
For this I’m comparing the British National Corpus and the Corpus of Contemporary American English. (They’re not 100% comparable, but they’ll do.) In the BNC, there’s on average 1 comma for every 20 words written. In COCA, it’s 1:15. So, there are a lot more commas in the American corpus. (I tried this on the GloWBE corpus too, and got about 10% more commas in AmE than BrE–but it’s harder to know in GloWBE that the writers are from the country that they’re categori{s/z}ed in.)
