fishingarkansas,
I don't post here often for this exact reason, people often take simple questions out of context. I believe you meant you wanted the simple terms, I will gladly share what I have learned. Most of the simple terms below all come from fly tying in some way. The ones I have listed are ones that I had trouble figuring out when i tried to learn more as you are obviously doing. You may already know some of them. The more you learn - the more you know.
Barbules - Skip is correct with his info about the barbules, it pretty much is the soft part of a feather.
Palmer - Tying a hackle feather (or the new palmer chenille) on the hook shank and wrapping it around the shank so the feather sticks out in all directions.
Dubbing - A material that is used to create fly/jig bodies. It is usually fine hair or flash material chopped into very short length. You take a piece of wax and rub it on your thread to help the material to stick and then apply and twist the chopped hair to the waxed piece of thread. Make wraps of the 'dubbed' material and you have an instant buggy looking body.
Kip tail - It is simply calf tail. Have never understood why, but it seems fly tiers call it calf tail and jig tiers call it kip tail.
Flex Seal - a popular cement/glue that many use to seal their finish knots.
Zonkers - Rabbit hide with the fur on it that the hide is cut into thin strips. The term Zonkers refers to when the hide is cut with the direction of the hair and the term Cross-Cut is used when the hide is cut perpendicular to the direction of the hair. Zonks are often used for tails and cross-cut used for wrapping around the hook shank to make a body.
Grizzly - This term is often used when a material (feathers, fur, flash) has black lines that run across it making it look as though it has black bars.
Strung - As in strung marabou, strung hackle, strung peacock - is when the thick ends of a feather are lashed together with string to make it easy to keep a bunch of feather together. Easier than having a bag of loose feathers anyway.
Bodkin - A tool that is pretty much a needle with some type of handle. Use full for moving small items that are tied on a fly/jig.
Bobbin - The tool that holds your thread.
Lead Collar or Lead Barb - The section of a jig head that is used to hold plastic lures in place on the hook. Lead collars and barbs are often cut off when tying jigs.
I do strongly agree with both Skip and Snake that you do not need to know every term there is about fly tying to create a fly or jig that will catch fish, but it sure makes it a lot easier to learn from other more experienced tiers, tutorials and books when you do know and understand some of the more complex terms IMO. I wish I could post some pics of stuff, but haven’t figured that part out yet. I am always trying to learn anything I can and happy to share along the way.
If you need any other info, feel free to PM me.
