the.com/class

means A group of students taught together, a category things are sorted into, or the social rank someone's born into or climbs toward.

from From Latin classis, which named the ranks into which Roman citizens were divided for military and tax purposes — literally the 'calling up' of groups, from a root meaning to call or summon. It moved into French and English keeping that core sense of sorted groups, later splitting into schoolroom 'classes,' scientific 'classifications,' and the touchier business of social 'class' — all still ranks you get called into.
