The Spanish word 'grama' (meaning 'grass') comes from the Latin word 'gramen', which meant 'grass' or 'fodder'. It developed through the Latin plural form 'gramina' (meaning 'grasses') before reaching its current Spanish form. This is a straightforward evolution where the meaning has remained essentially unchanged from Latin to modern Spanish, continuing to refer to grass or grassy plants.

Several Spanish words are derived from the same Latin root, including 'gramínea' (referring to the grass family of plants) and 'gramíneo' (meaning 'grassy' or 'grass-like'). These technical terms are used primarily in botanical contexts but share the same ancient connection to grass.

English speakers might recognize this root in scientific terms like 'gramineous' (relating to or resembling grass) and 'Gramineae' (the former scientific name for the grass family, now known as Poaceae). While these aren't everyday English words, they share the same Latin ancestor as the Spanish 'grama'. The prefix 'gram-' in these botanical terms always relates to grass or grass-like plants.
