The word 赔率 is formed by combining the character 赔, meaning 'to compensate' or 'pay out', constructed from the radical 贝 (money) and the phonetic component 咅, with the character 率, meaning 'rate' or 'ratio'. Together, they create a compound where 赔 denotes the payout aspect and 率 specifies it as a numerical rate, resulting in the meaning 'odds' as in betting.
