- l-ənjbaṛ لنجبار "maize" was originally anjibār أنجبار "snake-weed" (Persicaria bistorta), whose flowers looks vaguely similar. This in turn comes from Persian angbār انگبار, which Corriente seems to derive from rang-bār رنگبار "many-coloured".
- skənjbir سكنجبير "ginger" derives from some sort of popular confusion between two Arabic words: zanjabīl زنجبيل "ginger" and sakanjabīn سكنجبين "oxymel" (a mixture of honey and vinegar used medicinally). I assume the connection is that both are good for colds, but a quick search didn't turn up any actual evidence that oxymel was used for that purpose. Sakanjabīn is apparently from Persian سرکه انگبین serke angabin (Corriente gives the form sik angubēn) "vinegar honey", while zanjabīl is apparently, again via Persian, from Sanskrit शृङ्गवेर śṛṅgavera.
- fərnəħ فرنح "smile, laugh (of a baby)": cp. Andalusi farnas فرنس, Moroccan fərnəs فرنس; possibly, Corriente suggests, from Greek euphrosynē εὐφροσύνη "joy".
- bu-mnir بومنير "seal" was very hard to elicit, since they've been locally extinct for decades (they've nearly disappeared from the entire Mediterranean, in fact). However, it turns out to be correct after all: cf. Andalusi bul marīn بل مرين "sea lion", Maltese bumerin "seal". Corriente seems to take this as Romance *pollo marino "sea-chicken", but the first part of that at least is clearly implausible in light of the comparative evidence as well as of common sense; the second might be tenable, but I'm not sure.
On a not entirely unrelated note: for anyone who wants to explore the maritime terminology of Dellys in greater depth than I've ever been able to elicit, El-Bahri.net is a wonderful and unexpected resource.
