Acorus Calamus - Etymology of calamus

Etymology of calamus

Cognates of the Latin word calamus (meaning "cane") are found in both Greek (kalamos, meaning "reed") and Sanskrit (kalama, meaning "reed" and "pen" as well as a sort of rice) — strong evidence that the word is older than all three languages and exists in their parent language, Proto-Indo European. The Arabic word qalam (meaning "pen") is likely to have been borrowed from one of these languages in antiquity, or directly from Indo-European itself.

From the Latin root "calamus", a number of modern English words arise:

• calamari, meaning "squid", via the Latin calamarium, "ink horn" or "pen case", as reeds were then used as writing implements;
• calumet, another name for the Native American peace pipe, which was often made from a hollow reed;
• shawm, a medieval oboe-like instrument (whose sound is produced by a vibrating reed mouthpiece);
• chalumeau register, the lower notes of a clarinet's range (another reed instrument).
