Etymology
From Old Latin aestumāre, from Proto-Italic *aistomāō, 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. The second element is then from Proto-Indo-European *temh₁- (“to cut”).
However, De Vaan finds this improbable and instead proposes a connection with Proto-Indo-European *h₂eys- (“to seek”), found in aeruscō (“to beg”).[1]
