pannus

Borrowed from Latin pannus (“cloth”). Doublet of pagne, pan, and pane.

pannus (plural panni or pannuses)

1. A hanging flap of skin or other tissue, especially one covering the cornea (in trachoma) or cartilage (in rheumatoid arthritis).
2. (meteorology) A type of accessory cloud, looking like shreds either attached to, or separated from, the main cloud formation; mainly associated with nimbostratus, cumulus, and cumulonimbus.
3. (medicine) A tent for a wound.
4. (medicine) A birthmark on the skin.

• (cloud): scud

• sannup, unsnap

Possibly from Proto-Indo-European *peh₂n- (“fabric”), or, in view of the unusual vowel length alteration and geminate -nn- in Latin, from a widespread European substrate. Cognate with Ancient Greek πῆνος (pênos, “web”), Gothic 𐍆𐌰𐌽𐌰 (fana, “piece of cloth”), Old English fana (“flag”), English fane.^[1]

• (Classical Latin) IPA^(key): [ˈpan.nʊs]
