Ammobium, pronounced [aˈməʊbiəm], is a word that comes from the Greek root "ammo-" meaning sand and "-bios" meaning living. The spelling of the word is derived from the ancient Greek spelling and follows the English spelling rule with the doubled 'm' before the 'o' to indicate a short vowel sound. The 'b' after the 'm' represents the bilabial stop sound /b/ and the final '-ium' is a common suffix for scientific names of organisms, indicating that ammobium is an organism that can survive in sand.
The word "ammobium" has a botanical origin. It comes from the genus name Ammobium, which is derived from the Greek words "ammo" meaning "sand" and "bios" meaning "life". The name is apt as plants in the Ammobium genus typically grow in sandy habitats.
