CANOE

The acronym CANOE is an etymological joke, referring to the Committee to Attribute a Nautical Origin to Everything. Many English words do come from nautical terms, because English spread around the world first on ships, headed for Bermuda, Canada, India, Australia, or Pitcairn Island. But people got completely carried away with this, with "Port Outward, Starboard Home," or "Shipped High In Transit," neither of which is the real origin of those terms*. Acronyms did not come into being until such things as RADAR and SCUBA** in the 1940s. Also, there is no such Committee.

There are romantic notions that seem to be culturally installed, so that phrases are often falsely attributed to "Shakespeare's time," or "gambling slang," or "originally Irish." Those are red flags (which is a nautical term) that the purported explanation may be invented. As for the Irish in particular, I wrote about that almost twenty years ago There's a Sach Ur Born Every Minute.

*Posh is an old term for a dandy, based on a thieves cant word for coins. Shit occurs in other Germanic languages, likely derived from a a verb meaning "to snip." Which makes sense if you are spending a lot of time around sheep, dogs, or other mammals.

**SCUBA means Self-Contained Underwater Breathing Apparatus. TUBA is also an acronym, meaning Terrible Underwater Breathing Apparatus.
