Is it minuscule or miniscule?: Usage Guide

The adjective minuscule comes from the Latin word minus ("smaller"), but associations with mini- ("smaller or briefer than usual, normal, or standard") have produced the spelling variant miniscule. This variant dates to the end of the 19th century, and it now occurs commonly in published writing, but it continues to be widely regarded as an error.
