I'm going to be giving a talk here at g4g on definitions in twisty puzzles. To that end, it would be helpful if people could suggest what terms they think should be included (twisty, doctrinaire, jumbling, fudging, boubleized, etc.) and links to original posts mentioning those terms and epoch flame wars about their meanings so I don't miss anything. Thanks in advance.

I assume that you have read Oskar's talk here?

Also, don't forget pillowing, as this sometimes necessary to make a functional mechanism, not just for aesthetic reasons. I guess Andreas will have more suggestions.

define 'pretty' Bram.

Enjoy the g4g all of you who are going. I do so wish HK and the states were a bit closer. Ah well, I'll have to save my fun until another day and wait for the posts and photos!

How about the group-theory-based terms:

Orbit
Commutator
Conjugate
Subgroup
Parity (parity of reduced groups, true odd permutations, excess twist)


It would be nice to talk about some of the properties of puzzles and pieces such as:

Orientation of pieces
Chiral pieces
Deep cut puzzles (a few definitions, getting into these may be outside of the scope of your talk)
Types of slices (for example Master Skewb / 3x3x3 slices versus Gigaminx slices)
Super-stickers / supercube


It would be nice if you could undo the very wishy-washer misused "algorithm" term that so many folks use to describe any memorized sequence of moves they use on a puzzle. It might be worthwhile to show the varying uses in the terms "master" / "professor" / "elite" / "royal" etc. and hopefully discourage their use.

It may be nice to cover different move-counting metrics such as quarter-turn versus face-turn metric and discuss the competition for fewest moves solves.

Traditional mechanism (cylinder) vs. V-mech (spheres and cones).

Now some of my notes with "highly sophisticiated theory threads" (partly sarcastic) come in handy:
On the order of twistypuzzles:
viewtopic.php?f=1&t=15258
I quited using the term "order" and use "number of cuts per axis" instead but you asked for debates and this fits.

Deep cuts:
viewtopic.php?p=181860#p181860

Multi-Puzzles:
viewtopic.php?f=1&t=14875
With the most prominent example: TomZ's Multidodecahedron.

Not about a specific term but still interesting to read (for me):
viewtopic.php?f=1&t=15614
including a shameless self-advertising:
viewtopic.php?p=190396#p190396

Virtual pieces and imaginary pieces:
viewtopic.php?p=191376#p191376
Nowadays I prefer "Zero volume holding point pieces" and "non holding point pieces" but that is just me.
Derived from there the "Complex XYZ" is defined.

Mixup:
viewtopic.php?f=1&t=22272

I tried several times to introduce the term "restricted" compared to bandaged:
viewtopic.php?p=244313#p244313
And there is the term "hidden cuts". Sadly I do not find it.
Carl Hoff: Can you help me finding it?

Parity:
viewtopic.php?f=8&t=22201

Does this suffice?

Oh yes!
