Etymology
The adverb "rigidly" is built upon the adjective "rigid," which entered English in the late 15th century from the Latin rigidus, meaning stiff or unyielding. This Latin term derives from the verb rigēre, "to be stiff," a root that can be traced back to the Proto-Indo-European base reig-, suggesting tension and stiffness. The suffix "-ly," of Germanic origin, is a prolific adverb-forming element in English. Thus, the literal construction "in a stiff manner" evolved to describe both physical inflexibility and, more abstractly, strict adherence to rules or principles without deviation.
