Etymology

[edit]

Diminutive of māla (“the cheekbone, jaw”), from its reconstructed Proto-Italic form *smakslā[1] and the diminutive suffix *-elos via the following sequence of regular sound changes: *-kslelā > *-ksl̥lā > *-ksillā.[2] Compare the formation of the following diminutives: āla–āxilla, ōlla–auxilla, paulus–pauxillus, pālus–pāxillus, vēlum–vēxillum. An alternative etymology of māla, supported by Thurneysen and Leumann, reconstructs its original form as *mandslā, from the root of mandō (“to chew”); if this is correct, the -x- in the diminutive must have instead been introduced by analogy to āxilla.[3][4] Synchronically, māxilla can be viewed as ending in the Latin diminutive suffix -illus.

      • Aulus Cornelius Celsus, De Medicina 8.1:
        Maxilla vero est molle os; eaque una est, cuius eadem et media et ima pars mentum est, a quo utrimque procedit ad tempora; solaque ea movetur: nam malae cum toto osse, quod superiores dentes exigit, immobiles sunt.
        • 1938 translation by W. G. Spencer
          But the lower jaw is a soft bone and a single one, of which the chin forms the middle and lowest portion, whence it is continued on the two sides to the temples; and it alone is movable, for the cheek-bones with all that bone which produces the upper teeth are immobile ― published online at LacusCurtius by Bill Thayer as Celsus: On Medicine, Book VIII
      • Aulus Cornelius Celsus, De Medicina 4.7:
        Si per haec parum proficitur, ultimum est incidere satis altis plagis sub ipsis maxillis supra collum, vel in palato citra uvam, vel eas venas, quae sub lingua sunt, ut per ea vulnera morbus erumpat.
        • 1938 translation by W. G. Spencer
          If there is little effect from these remedies, the last resource is to make sufficiently deep incisions into the upper part of the neck under the lower jaw, or into the palate in front of the uvula, or into the veins under the tongue, in order that the disease may discharge through the incisions. ― published online at LacusCurtius by Bill Thayer as Celsus: On Medicine, Book IV
