Perseverance commonly suggests activity maintained in spite of difficulties or steadfast and long-continued application: Endurance and perseverance combined to win in the end. It is regularly used in a favorable sense. Persistence which may be used in either a favorable or an unfavorable sense, implies unremitting (and sometimes annoying) perseverance: persistence in a belief; persistence in talking when others wish to study. Tenacity with the original meaning of adhesiveness, as of glue, is a dogged and determined holding on.

Pertinacity unlike its related word, is used chiefly in an unfavorable sense, that of overinsistent tenacity: the pertinacity of the social climber.
