Neoclassicism in Architecture
Neoclassical architecture rejected Rococo ornamentation and drew inspiration from Greek, Etruscan, Roman, and even Egyptian art. Religious architecture declined, and public buildings like libraries, museums, and arcades were constructed.

Elevation
The flat representation of a building facade, the side of a machine, or an object through geometric projection, regardless of perspective. It maintains all proportions and is obtained by parallel projection perpendicular to the plane of projection. Elevation, along with the plan, is one of the main representations in the dihedral system.
Dimensional
Something is two-dimensional if it has two dimensions, for example, width and length, but not depth. Planes are two-dimensional and can only

5.3 Language Development in Early Childhood
Introduction
Language is fundamental for cognition in early childhood, from 2 to 6 years old. It’s a major cognitive achievement during these years. Children begin this period with short sentences and a limited vocabulary, but by age six, they can understand and discuss almost anything.
Brain maturation, particularly in specific areas, and the necessity of language for social interaction make ages 2-6 the primary period for language learning. Early childhood
