Some linguists (e.g., Hamp 1990) believe the verb comes from an unattested noun *ajes-tomo- "who cuts metal," from æs "bronze" and *temos "cut." This is not followed by de Vaan (2014), who writes that if the word is of native Indo-European stock, then "it seems more likely that æstumare is connected with the [Proto-Indo-European root] *h2eis- 'to seek' found in aescāre 'to beg'."
