Definition from zikkir, the free dictionary
Thrice (not comparable)
- Unlike once and twice, thrice is somewhat dated, often used for a comical or intentionally archaic effect. Three times is the more standard usage. On the other hand, once and twice are almost always preferred over one time and two times except when needed for parallel structure (e.g. when listing "one time, two times, three times"). Thrice does however retain some currency in compounds like thrice-monthly.
