From,. Anderthalb is the single surviving relic of an older system to describe fractions, which counted from the higher ordinal number rather than the lower cardinal. Compare 🇨🇬, 🇨🇬, 🇨🇬. Compare also the use of the word in the sense of a half-hour before the following hour, such as halb zwei to mean one thirty. The word has since lost the meaning "second", being used solely as "other" in modern German.
