Translation: number; numeral; figure; digit (noun)
Etymology: From Ancient Greek ἀριθμός (arithmos), meaning 'number' or 'count'. This is the direct source of English 'arithmetic' and 'algorithm' (via Arabic al-Khwarizmi). The word shares the same Indo-European root *h₂reyH- meaning 'to fit together' or 'to count', which also gave rise to Latin 'ratio' and English 'reason'. The Greek word has maintained its core meaning unchanged for over 2,500 years, making it one of the most stable mathematical terms across languages.
Mnemonics
- Think 'arithmetic' - both start with 'arith-' and relate to numbers
- Remember 'algorithm' also comes from the same mathematical family
