lowercase

The term originates from the early days of manual typesetting. Printers stored the metal type for capital letters in the upper, more accessible case of a two-case typecase, while the smaller, more frequently used letters were kept in the lower case. This physical arrangement of the 'lower case' gave its name to the letters contained within it. Over time, the compound word evolved from a literal description of a storage box to an abstract typographical term for small letters. The logic perfectly captures how a practical, spatial distinction in a trade became the standard linguistic term for letterforms.

Structure: lower + case lower (english, comparative form of 'low', indicating position); case (english, from old french 'casse', a box or receptacle, here referring to a tray for holding type).
