From Old Latin aestumāre, whose origin is uncertain. Usually explained as aes ‎(copper, bronze) +‎ *temos ‎(cut), so “one who cuts copper”, meaning one in the Roman Republic who mints money. De Vaan find this not credible and proposes a connection with the Proto-Indo-European root *h₂eis- ‎(to seek) found in aerusco ‎(to beg).
