The Spanish word 'bebida' (meaning 'drink' or 'beverage') comes from the Spanish verb 'beber' ('to drink') combined with the past participle suffix '-ida'. The verb 'beber' itself derives from the Latin verb 'bibere', which also meant 'to drink'. When the past participle suffix '-ida' is added to 'beber', it creates a noun referring to the thing that is drunk - a beverage.

The most obvious related Spanish word is the verb 'beber' (to drink), which is simpler and more commonly encountered by Spanish learners. This is the base verb from which 'bebida' is derived. You might also encounter words like 'bebedor' (drinker) or 'bebible' (drinkable), all sharing the same root.

While English 'beverage' might look similar to 'bebida', they're not actually related. However, English has borrowed some scientific terms from the same Latin root 'bibere', such as 'imbibe' (to drink or absorb) and 'bibulous' (highly absorbent, or fond of drinking alcohol). These are rather formal or technical words, but they share the ancient meaning of drinking or absorbing liquids.
