musio

Latin

Etymology

Unknown. No actual classical uses are known, but the word is included by Isidore of Seville in his Etymologiae, where it is stated that the word is a new creation from mūs (“mouse”) since cats catch mice; however, Isidore's etymologies are usually unreliable. Compare Latin mūstēla.

Noun

mūsiō f (genitive mūsiōnis); third declension (hapax)

1. cat
   • c. 600 CE – 625 CE, Isidorus Hispalensis, Etymologiae 12.2.38:

     Mūsiō appellātus, quod mūribus īnfestus sit. Hunc vulgus cattum ā captūra vocant.

     [A cat] is called mūsiō because it is deadly to mice. People call it cattus from catching.

Usage notes

• Gender and inflection are unattested. Gaffiot gives it as "mūsiō, ōnis, m.", Georges as "musio, ōnis, f.".
