Ashlar is dressed stone work of any type of stone. Ashlar blocks are large rectangular blocks of masonry sculpted to have square edges and even faces. The blocks are generally 13 to 15 inches in height. When smaller than 11 inches, they are usually called "small ashlar".
Ashlar blocks are used in the construction of many old buildings as an alternative to brick. Generally the external face is smooth or polished, occasionally it can be decorated by small grooves achieved by the application of a metal comb, this is usually only used on a softer stone ashlar block. This decoration is known as mason's drag.

An autostereogram is a single-image stereogram (SIS), designed to trick the human brain into perceiving a three-dimensional (3D) scene in a two-dimensional image. In order to perceive 3D shapes in these autostereograms, the brain must overcome the normally automatic coordination between focusing and convergence.

Mealy-mouthed may come from a saying such as German Mehl im Maule behalten, “to carry meal in the mouth, that is, not to be direct in speech,” which occurs in Luther's writings. In English we find the terms mealmouth (1546) and meal-mouthed (1576) recorded around the same time that we find mealymouthed (around 1572). Mealy-mouthed is the only form that survived to describe this trait described by Luther, which not only survives but flourishes in our time.

In the other general sense, tranculturation is one aspect of global phenomena and human events.
