There are four central aspects to the Latin numeral:
- The cardinal: ūnus, duo, trēs, quattuor
- The ordinal: prīmus, secundus, tertius, quārtus
- The distributive: singulī, bīnī, ternī, quaternī
- The adverb: semel, bis, ter, quater
What is are numeral adverbs?
- Like English numeral adverbs, Latin numeral adverbs answer the question ‘how many times was something done?’
- How many times does Scylla engulf the strait each day? Thrice. [She does action x three times.]
[Side note: I first discovered the word ‘thrice’ while reading Homer in 6th grade. It’s probably the only moment of ‘word recognition’ that I can remember having. Does anyone else have stories about learning new words as a kid? I’d love to hear them in the comments.]
