In English there are many. Some of them have an interesting historical meaning or explanation, while others are completely baffling. The connection between the words, and what they represent is often obscured by history and common usage.
For example, take the expression "three sheets to the wind."
This is, as most English speakers will tell you, another way of saying that someone is drunk.
The meaning of this expression originates from England's heritage as a great naval power, as do many of the language's most common and colourful expressions.
The original phrase was actually "three sheets IN the wind." This might seem like a minor distinction, but when you stop to consider what the phrase is actually saying, it makes perfect sense.
The 'sheets' aren't sails, as you might expect, but lines or ropes. These are fixed to the lower corners of sails to hold them in place. If three sheets are loose and blowing about in the wind then the sails will flap about uncontrollably . . . like a drunken sailor.
Hence the metaphor "three sheets to the wind" being applied to anyone who has had one drink too many.
Since we are on the topic of England's sailing past, some other linguistics tidbits are:
Being 'all at sea' to mean confused or lost. This one does not need any explanation, I feel. But the next may.
Being 'taken aback' to mean being surprised, comes from when when the boat points into the wind and the sails press against the mast, and forward progress is suddenly stayed. This may also lead to being 'in irons,' which occurs when forward momentum is lost.
A very common expression is 'the cat is out of the bag.' This is usually taken to mean that some secret is now out in the open. However, the cat in question is actually the 'cat of nine tails,' or a very nasty type of whip. This was used to keep order on the navy boats, and to dish out punishment. It was greatly feared. If the cat is out of the bag, then someone is about to get a very nasty surprise indeed.
Of course, now that we know that the 'cat' in question is actually a whip and not a member of the species Felis silvestris catus, then this next expression takes on a whole new meaning;
I am sure you have heard people say of a small house, or apartment, that there is 'no room to swing a cat.' This colourful expression means pretty much the same to us, as it did to 18'th century sailors. Simply, there is not much room.
During a punishment detail, all the sailors were called on deck to bear witness. In the case of a ship with a full complement on board, this could make for a very crowded deck. In fact the deck could be so crowded that the cat o' nine tails could not be used without hitting the observers, so there was literally 'no room to swing a cat.'
Well, that was a fun walk through linguistic history. But let's have just one more.
'Swinging the lead.' This expression is taken to mean that someone who is doing this is being lazy and not working hard. 'Swinging the lead' is quite literal. Before depth sounders were invented, the only way to tell the depth of any water was to measure it. This was done with a line with a lead weight. The line would have knots on it at regular intervals, and the sailor would count the knots as the line fed through his hands.
The job was considered very easy and whoever did it was often accused of taking more time than was necessary and therefore being lazy. Therefore anyone who took longer than required to accomplish a task was 'swinging the lead.'
Well, this was a very limited review of nautical expressions in English. Just to give you an idea of how many more there are, take a look at this list. I am sure that you will recognise some of them. I can say that I have used probably close to 25 of these expressions, at one time or another, and I am particularly fond of several.
