As I mentioned in the last post, I spent January in Australia, where there is virtually no word too short to be abbreviated. One of the most prominent is the first meal of the day, which is rendered as “brekky.” Or “brekkie.”

I saw both versions with what seemed like equal frequency. Unsurprisingly, there’s been debate on the issue, as in this article (which punted) and a Perth subreddit where someone posed the question: “Brekky, breaky or brekkie?” Most of the answers were facetious, but among the serious ones, “brekkie” beat out the “brekky” by a score of 3-2. “Breaky” does sometimes show up in the wild but, as some of the commenters pointed out, it’s been contaminated by the Billy Ray Cyrus song “Achy Breaky Heart.”
According to Corpus of Global Web-Based English (GloWbE), Australia leads the world in the use of both terms, with “brekky” being slightly more popular. Here’s the chart for “brekkie”:

Although Australia has outstripped both countries, the abbreviations started out in Britain and Ireland. The OED has a quote from the 1904 children’s book The Phoenix and the Carpet, by E. (Edith) Nesbit: “I’ve brought your brekkie, and I’ve put the little cloth with clover-leaves on it.” And in Elizabeth Bowen Ann Lee’s (1926), “Do call poor Bingo in..and give him his brekky.” Bingo is a spaniel. The first use in reference to adults I’ve seen is Green’s Dictionary of Slang’s citation of a line from Joyce’s Ulysses (1922): “And then, when they settled down in a nice snug and cosy little home, every morning they would both have brekky, simple but perfectly served.”
In her youth, in the same period as the Bowen and the Joyce, Elizabeth, later the Queen Mother, was partial to yet another variation. From her diary:

My sense is the words took off in Australia in mid-century but lay dormant in Britain till the 2000s, when both rose sharply, especially “brekkie.” Here’s a Google Ngram Viewer chart showing use in British English:

America has lagged behind, obviously.. GloWbE, which tracks usage in 2013-14, shows nine “brekkies” in U.S. sources, but even that’s deceiving, as most of them are quotes from Brits or Australians. However, there’s been a slight uptick in recent years, and I’ve labeled the terms “On the Radar” instead of “Outliers.” Here’s a graphic from a U.S. kids’ news service, posted just last week:

And Denver Post sports columnist Mark Kiszla wrote this in 2021: “The best breakfast in the world is a freshly baked almond croissant, eaten on a ski lift in Val d’Isere, France. Got get up early and move fast if you want to brekky with me, pal.”
