Bricks

• Bricks - The iconic part! Studs and anti-studs, with only right angles and no height change or curved surface. See Technic Bricks for bricks with holes
• Bricks Curved - A brick that has height change with a curved surface. Curved edges do not qualify for this category and should be found in Bricks Round and Cones. Arches are included in this category. There is crossover with other Brick categories, espcially Round and Sloped.
• Bricks Round and Cones - A brick that is spherical or has a rounded edge. There is crossover with other Brick categories, espcially Curved and Sloped. If a rounded brick has a height change, the round feature takes priority when categorising the part so you will find Curved and Sloped parts such as 24599 Brick Round Corner 5x5x1 in the round category not in the Curved category. 
• Bricks Sloped - A brick that has height change with a straight (or flat) surface. Sloped edges/sides do not qualify for this category and should be found in Bricks Wedged. There is crossover with other Brick categories.
• Bricks Special - A brick that has other features such as clips, pins, hinges, or studs on sides. You may also find parts here that appear to be plates but are actually to large too be categorized as such.
• Bricks Wedged - A brick that has angled sides that are not just 90°. There is crossover with other Brick categories, espcially Curved and Sloped. The wedge shape of a brick takes priority over height change so if a part has both features it will be in here not Sloped or Curved.

Plates

• Baseplates - Plates that have no anti-studs (which means you cannot connect the bottom of it to the top of a plate or brick). They may be flat, have raised areas, or have no studs.
• Plates - No more than 2/3 height of a standard LEGO Brick. Plates are Tiles with studs. Angled and Round Plates have their own catagories. If you can't find a plate here also check Bricks Special for parts that seem like plates but are too thick to be categorised as such.

Dishes are also kept here, a dish is usually smooth and slightly domed with at least one stud in the centre. The height and studs differentiate them from Round Bricks or Domes. However some dishes can be found with no studs but have bars that allows construction with them, the height of these studless plates differentiates them from Domes.
• Plates Special - An all encompassing category that contains any part that features at least a 1x1 plate in it. Special Plates can feature clips, brackets, steps, pins, ball joints, bars, wheel connectors, etc... Jumper plates (a 1x2 plate with only 1 center stud for example) are also kept here.
