Now here’s an interesting trio of homonyms. The first spelling is by far the less known of the two, and has two meanings.
And, of course, a bite is the one you accomplish with your teeth :-), and a byte will be familiar to you from computer terminology, normally consisting of 8 bits of information and being the smallest memory segment address.

BightLoopElbow2. The second meaning is similar, and refers to a loop made in a rope, usually prior to  making some kind of knot. Here is a picture showing a bight, and a few other rope-users’ terms. Knot tying is such an old and complex subject that much of the terminology is known only to sailors and other people who spend a lot of time with rope. If you are interested in this ancient art, I recommend “The Ultimate Encyclopedia of Knots and Ropework” by Geoffrey Budworth.

I love the sea and sailing, and incidentally love working with ropes too. Even when I was driving lorries when I was young, I much preferred to secure my load with ropes, rather than the straps which were beginning to take over. I don’t even know the correct name for the knot I used ( as the ‘trucker’s hitch‘ is a little different), but it was taught to me by an old hand and worked like a winch, hauling the rope much tighter than I could have done by my own strength.
