Numbers and Numerals

Numbers and Numerals

• as in English, there are number words and symbols (Roman numerals) to express numbers in Latin

• every number word in Latin has a corresponding Roman numeral

• numbers are technically adjectives, thus they modify nouns

• there are two “types” of numbers: cardinal and ordinal

– cardinal: one, two, three, four, etc. (used for counting)– ordinal: first, second, third, fourth, etc. (used for ranking)

number, and gender):– ūnus, -a, -um declined like a 2-1-2 adjective, with two exceptions– duo, duae, duo are declined sort of like 2-1-2 adjectives– trēs, tria is declined like a 3rd declension adjective

• numbers 4-100 are indeclinable, aka they don’t change endings to show gender, number, and case–BUT they still modify nouns, e.g.:– quinque puerī: five boys– quinque puellārum: of five girls– ā quinque oppidīs: from five towns
