Severo vs. rigoroso vs. rigido vs. ferreo
In Italian, the words severo, rigoroso, rigido, and ferreo all translate to strict or severe, but they carry distinct nuances. Choosing the right word depends on whether you are describing discipline, precision, inflexibility, or unbreakable strength.
Severo
The word severo is primarily used to describe people, punishments, or judgments that are demanding and show little leniency. It relates directly to authority and discipline, often implying a lack of warmth or tolerance for mistakes.

(You should not be so hard on yourself after a small mistake.)
Rigoroso
The word rigoroso means strict in the sense of being thorough, exact, and meticulous. It is often used for methods, logic, controls, or rules that require high standards, precision, and careful attention to detail without necessarily implying meanness.

Rigido
The word rigido literally translates to rigid or stiff. When applied to rules, schedules, or people, it means they are inflexible and incapable of bending, adapting, or making exceptions.

Ferreo
The word ferreo literally means made of iron, and metaphorically it describes something that is iron-clad, unbreakable, or extremely strict. It is used to emphasize absolute, unshakeable discipline, willpower, or rules that cannot be broken under any circumstances.

Summary
To summarize, use severo for demanding discipline and a lack of leniency in people or punishments. Choose rigoroso to highlight precision, thoroughness, and high intellectual or procedural standards. Opt for rigido when emphasizing inflexibility and a stubborn inability to bend the rules. Finally, use ferreo to describe iron-clad, absolute strictness and unbreakable willpower.
