Mt favourite word for today is thrice. It’s a word that everyone understands, but no-one actually uses. It has such a lovely sound. Once, twice, thrice. It rolls off the tongue beautifully.
Imagine, if you will, an argument: ‘I texted you twice, and you never replied!’ Perfectly normal. ‘I texted you thrice!’ No. It would just never be said. That’s such a shame.
I might try to start using it in normal conversation and try to revive an archaic word in my own personal vocabulary. It is a noble cause.
