adv. in an extremely thorough, strict, or precise manner
adv. with harshness or severity
The word "rigorously" traces back to the Latin "rigor," meaning "stiffness" or "severity," derived from "rigere" (to be stiff). The suffix "-ous" (from Latin "-osus") forms adjectives indicating possession of a quality, while "-ly" (Old English "-lice") converts adjectives into adverbs. Thus, "rigorously" evolved to describe actions performed with strictness or precision, retaining its core sense of inflexibility.
