Sticktoitiveness—meaning dogged perseverance—regularly appears in three forms: the unhyphenated form, stick-to-it-iveness, and stick-to-itiveness. The three-hyphened form was most common when the word came about in the U.S. in the late 19th century (as attested by the OED‘s examples and in historical news searches). But today, the two-hyphened stick-to-itiveness is most common, and the unhyphenated form is still comparatively rare. The last form is steadily gaining ground, though, and is likely to prevail in the near future, if the word stays in the language.
We assumed sticktoitiveness in all its forms would be most common in sports writing, but we were surprised to find it in other contexts (see examples below). Still, as a colloquial term, it might be considered out of place in formal writing. There are several good noncolloquial synonyms, including perseverance, determination, dedication, stamina, and persistence.
