Falcata, saunion and falarica...

[ParthianBow]

Latin is such an unknown quantity to me... hock:

Two of these words are Greek!
Falcata is a Latin feminine adjective meaning "curved". Pliny (e.g.) uses it to describe the shape of a rooster's tail feathers. There is a Latin word falx, which means a curved blade like a sickle. The plural of falx is falces.
Kopis is a Greek word meaning a "chopper" or "cleaver". One kopis, several kopides.
Saunion is a Greek word meaning "javelin". One saunion, several saunia.
Phalarica is a particular type of Iberian missile mentioned by Livy (21.8 ). Lucan calls it a falarica (Pun. 6.198). I have never seen it spelled falerica, which sounds plain wrong! As a good Latin first declension noun, the plural is phalaricae/falaricae.

Thanks for your help, Duncan! Greek, Latin, I wouldn't know, I'm sorry to say. :? It's all Greek to me, as I think a character in Asterix once said.
However, I do want to get the words correct, hence my asking. Thanks for the explanation of where falcata comes from, but you didn't say what the plural of the word is. I find it used a lot in the singular, referring to a curved Spanish sword, so I had presumed that there is a plural of it as well. Is this not correct?

Regarding your query about 'falerica': it may well be wrong, but no less than Theodore Ayrault Dodge refers to it thus on page 160 of his excellent book 'Hannibal'. Everywhere else I've seen the word used, it has been spelt falarica, though.
