The definition of perseverance
Merriam-Webster defines perseverance as "continued effort to do or achieve something despite difficulties, failure, or opposition; steadfastness." That definition centers on effort that continues in the face of resistance, whether that resistance is a setback, a failure, or active opposition. It’s a word usually reserved for effort worth admiring: the years someone spends training for a goal, the repeated attempts after a failure, the choice to keep going when quitting would be easier.
Is perseverance actually different from persistence?
Honestly, not by much. Perseverance and persistence are close enough in meaning that Merriam-Webster’s own thesaurus lists them as synonyms of each other, and most dictionaries define one partly in terms of the other. There’s no strong etymological or psychological research establishing a sharp, categorical split between the two. The real difference people are usually reaching for isn’t about what the words mean, it’s about how they sound.
The connotation difference, with examples
Perseverance tends to carry a positive, almost virtuous connotation. Say "her perseverance through years of setbacks" and it reads as admirable, the kind of thing you’d put in a recommendation letter. Persistence is more neutral, and depending on context it can even tip slightly negative. "The persistent error kept appearing" is just a description, no praise implied, and "he was persistent to the point of being annoying" makes the negative reading explicit. Same underlying idea, continued effort over time, but different emotional temperature depending on which word you pick.
Why we named the company Persistence
That neutral, plain-spoken quality is exactly why we went with "Persistence" rather than "Perseverance" for the company name. "Perseverance" would have leaned self-congratulatory, a word that announces its own virtue. "Persistence" just describes what the product does: it keeps at a task, reliably, without needing anyone to read moral character into it.

Key takeaways
- Merriam-Webster defines perseverance as "continued effort to do or achieve something despite difficulties, failure, or opposition; steadfastness."
- Perseverance and persistence are near-synonyms, not two sharply different concepts. Merriam-Webster’s own thesaurus groups them together.
- The real difference is connotation, not meaning: perseverance usually sounds admirable and virtuous, while persistence is more neutral and sometimes even mildly negative.
- We chose the plainer, more neutral word "Persistence" for the company name on purpose.
