Cams – bumps on a gear or shaft, transmitting motion to other gears.
Crown wheel — a gear, with cams fixed at 90 degrees.

Cage gear (lantern gear, lantern pinion) — two wheels, one above the other, connected by planks.

Spur wheel — wheel with teeth looking to the outside.

Sail — inclined surface, converting translational motion of the wind to rotary motion of the shaft.
Windshaft — a shaft which holds the sails, horizontal or inclined.
Brake wheel — a gear (always crown wheel) that gives energy to vertical shaft or spindle. Held by a brake.

Vertical/upright shaft – the shaft of the smock windmill, which transmits the rotation from the windshaft downwards.
Wallower — a gear (cage or spur) at the top of vertical shaft that gets energy from brake wheel.
Great spur wheel — a gear (always spur) at the bottom of vertical shaft that gives energy to stone nuts.

Millstone — heavy cylinder with notches, rubbing grain using its weight and rotation.
Couple of millstones — a pair of millstones with all equipment, a unit of grain processing into flour.
Runner stone — the topmost of the pair of millstones, concave, is moved by the wind.
Bed stone — the bottom of a pair of millstone, convex. It never moves.
Spindle — iron thick rod, which holds the runner stone.
Stone nut — a gear (spur or cage) on the spindle that gets energy for millstones.

Tailpole — a system of logs, serving to turn the sails under the wind
Shingle — thin plates of wood
Hopper — rigidly suspended box for filling grain from the sacks
Frame — type of construction, the walls of which consist of beams with paneling
Kuritsi — sticks with hooks at the end, usually spruce trunks with a root
Shins — cross-beams of rams, which are used to raise rams for a new cycle
Sailcloth — cloth which is stretched on a sail
Rams — heavy beams, falling down and crushing the grain with their weight
Vat — the box surrounding the millstones, takes the flour, poured from them
Trestle – a type of log construction, in which the logs lie not tightly, but space between each other
Log consruction — the type of construction in which logs are stacked one on the other, forming walls
Post-based mill — a mill, in which it is possible to turn the whole barn to face the wind
Crushing bank — a closed box where the grain is crushed
Sheath — thin boards that protect the construction, but do not make it more rigid
Crushing system — a crushing bank and rams with all the necessary details, a unit of processing grain
Shaker — a bar that connects a shoe and a runner stone to dose grain
Shoe – movable boxes suspended under the hopper
Mealspout — a tray along which the flour is poured from the vat into the sack
Smock — a mill, in which it is possible to turn the cap of the barn to face the wind
