Nautical Terms
OK, if we are going down the road of explaining how nautical life leaked into the English language, here are a couple of more for you:
Scuttlebutt - as in "what's the scuttlebutt? a phrase generally accepted to mean what's the rumor mill saying or what's the "water cooler" talk around the office saying.
In old English, a Butt was a barrel and a Scuttle was a hole cut into the barrel for access. Every sailing ship had a large barrel of drinking water strapped to the mainmast. This barrel had a hole (or scuttle) just large enough to fit your hand and a ladle. Every day, sailors and passengers would convene around the water barrel to get their daily ration of drinking water and naturally, share the ship's going-ons with each other. Very much like the water cooler office talk of later years. Hence the phrase "what's the scuttlebutt?"!
By and Large. Now here's a common phrase people use all the time but never real know what it means. Most people use to mean something all encompassing, or like everything taken into consideration or in general. Its really a contradiction in terms though that comes from the days of the square masted sailing ships.
Sailing BY the wind means sailing at an angle into the wind. Sailing LARGE means the wind is abaft your beam (coming from behind) and thus pushing you forward. Sailing BY the wind was very challenging for square sailed ships, sailing large was much easier and preferred.
So the term BY and LARGE pretty much means from one end to the other or from one extreme to another.
I could go on as there are dozens if not hundreds of similar sailing terminology examples but I think I'll head home and get "three sheets to the wind" !
