The Spanish word 'comida' (meaning 'food') has its roots in Latin. It comes from the Latin verb 'comedere' meaning 'to eat up', which was formed by combining two elements: the prefix 'com-' (meaning 'together') and the verb 'edere' (meaning 'to eat'). The Latin 'comedere' evolved into the Spanish verb 'comer' (meaning 'to eat'). The past participle of 'comer' is 'comido' (meaning 'eaten'), and when combined with the feminine suffix '-a', it formed 'comida', which came to refer to food itself rather than just the act of eating.

Several common Spanish words are related to 'comida' through their shared root. The most basic is the verb 'comer' (to eat), which is one of the first verbs Spanish students learn. The word 'comedor' means 'dining room', and 'comestible' means 'edible' or 'food item'. All these words share the same Latin root emphasizing the concept of eating.

While English doesn't have many direct cognates from Latin 'comedere', we can find related words through the Latin 'edere' (to eat). English words like 'edible', 'inedible', and 'comestible' (though this is rather formal) share this connection. The prefix 'com-' seen in 'comida' is the same prefix we see in many English words like 'combine', 'companion' (literally, one who shares bread with another), and 'company', all carrying the sense of 'together' or 'with'.
