From deep inside another thread:
Thanks for the clarification. And no, when it comes to hybrids, you most certainly have read more than me.
Anyway... if core = core+springs+centers is truly standard usage here, I hope everyone can see why that is really illogical and confusing. Saying A=A+B+C is just... argh! Whenever I saw someone say "this core is awesome" I thought "WTF it's not touching anything but the centers, how can it matter much if at all?!?". Now I suspect they abused the word "core" like mentioned above.
Outside of hybrids, I see no need need to refer to core+springs+centers and quite frankly I wouldn't be surprised if indeed it was the hybrid guys who came up with such deformed terminology. And I can see it contaminating other areas so I'd like to clear this up and ask them to not misuse the word "core" like that anymore. We should have a wiki page about this hardware terminology, here are a few suggestions:
----------------------
Piece: A single piece of a puzzle, usage depends on the context. For example in solving a 3x3x3, usually only the 8 corners and 12 edges are considered. When listing the contents of a DIY set, one might include the core, screws, springs, washers and caps. Often we omit "piece" and for example say "edge" rather than "edge piece".
Corner: Corner piece of a puzzle, usually has three sticker sides but can have more. Examples: The 3x3x3 has 8 corners, the megaminx has 20.
Edge: Edge piece of a puzzle, has two sticker sides. Examples: The 3x3x3 has 12 edges, the megaminx has 30.
Center: Center piece of a puzzle, has one sticker side and is inside of a layer surrounded by edges and corners. Examples: The 3x3x3 has 6 centers, the megaminx has 12, the 5x5x5 has 54 (nine on each side).
Core: The central piece inside a puzzle, usually not visible. Examples: The 3x3x3 core is the thing with six holes for the screws, the Rubik 4x4x4 core is that ball with those eight round triangles, the void cube kinda of doesn't have a core.
Tip: Usually refers to an add-on thing that just rotates in place. Example: The pyraminx has 4 tips.
Frame: Single piece or combination of pieces that make up a basic frame of a puzzle in which the other pieces can be moved around. Examples: The 3x3x3 frame is its core and centers (including screws & co), and the edges and corners move around in it. The Rubik 4x4x4 frame is just its core, the void cube frame is made up of those inside pieces that don't move around when making outer layer turns, and the holey megaminx frame is that alien ball with holes and arms.
Fittings: Screws, springs, washers, ball-bearings, etc.

On the wiki page, the written examples would better be amended by pictures.
