"Thrice" vs "three times"
Are there any situations when you prefer "thrice" to "three times"?
The norm here is to say once (rather than one time) to say three times(rather than thrice) in current usage. Thrice is definitely old-fashioned, although you may still come across it in certain contexts:
This vehicle travels at thrice the speed of sound.
They play football thrice weekly.
Better to say:
This vehicle travels at three times the speed of sound.
They play football three times a week and train every night.
When it comes to twice, this is more often used than two times, although two times is also quite common in informal usage. Compare the following:
I’ve visited her twice already this autumn and she’s visited me once.
I’ve visited her two times already this autumn and she’s visited me once.
