tolero.

Uncertain. Perhaps from the root Proto-Indo-European *telh₂- (“to bear, carry”). * Perhaps the root *telh₂- formed an *-es stem noun *telh₂-s, which was then suffixed with *-eh₂yéti to create a denominative verb *tolh₂-s-eh₂yéti. This verb may have evolved into Proto-Italic *tolazāō, which then evolved into the Latin verb. * Alternatively, it may have evolved from a denominative verb to *tl̥h₂rós, itself composed of the root and the suffix *-rós (if this etymology is accepted, it may be related to Ancient Greek τάλαρος (tálaros)). * Perhaps a sā-present from Proto-Indo-European *telh₂-sah₂-. Compare other sā-presents, such as Latin axō * Perhaps a denominative to an otherwise unattested noun. If so, it may have been formed in a manner akin to Latin generō. However, Nussbaum rejects this analysis, as the oblique stem *teles- (akin to the oblique stem gener- of genus) would not have provided an *-o- to a denominative verb formed form the noun. Nussbaum concedes that the *-o- could have been added due to the influence of the perfect stem *(te)tol- or the adverb tolūtim, although he considers this unlikely. Compare Ancient Greek τλάντος (tlántos, “bearing, suffering”), τολμάω (tolmáō, “to carry, bear”), τελαμών (telamṓn, “broad strap for bearing something”), Ἄτλας (Átlas, “the 'Bearer' of Heaven”), Lithuanian tiltas (“bridge”), Sanskrit तुला (tulā, “balance”), तुलयति (tulayati, “lifts up, weighs”), Latin tollō (“to bear, support”), tulī (“to bore”), lātus (“borne”), tellūs (“bearing earth”), Old English þolian (“to endure”) (English thole), Old Armenian թողում (tʻołum, “to allow”).
