   • 2019 November 6, Mother Clouds, in Atticus Review

   • 2020 May 27, MrNonam3 (username), in What is the difference between mutatus and genitus clouds?:

     It is kind of hard to difference but a genitus cloud is a totally newborn cloud that comes from a previous cloud and mutatus is more the previous cloud that transformed into another. For example, an altostratus coming from a cirrostratus, is mutatus because it is the same cloud, just denser and lower. It transformed so much that it can't be cirrostratus. But a cirrus spissatus that comes from a died thunderstorm is genitus because the cumulonimbus died while some of its upper parts began to be another, totally different cloud.

語源

Perhaps from Proto-Italic *genatos, from Proto-Indo-European *ǵenh₁-tos, which displaced the original *ǵn̥h₁-tós, whence Latin nātus, which came to belong to a different verb. The term might connect to Oscan 𐌂𐌄𐌍𐌄𐌕𐌀𐌝 (genetaí), though the second -e- vowel of this form is unexpected.
