The Spanish verb 'premiar' (to reward) comes from the Latin verb 'praemiari' meaning 'to reward'. This Latin word was formed by combining two elements: the prefix 'prae-' meaning 'before, in front' and the verb 'emere' meaning 'to take or obtain'. The combination suggests the concept of something given or taken beforehand, which evolved into the notion of a reward.

Some related Spanish words include 'premio' (prize or reward), which is the noun form of 'premiar'. Another related word is 'premiado' (awarded, rewarded), which is the past participle of 'premiar'. These words share the same Latin root and maintain similar meanings around the concept of rewards and recognition.

While English doesn't have direct cognates of 'premiar', we can find some related words through the Latin 'emere' component. English words like 'redeem' (to buy back or recover) and 'exempt' (to take out, remove from obligation) contain this same Latin root 'emere' meaning 'to take or obtain'. The prefix 'pre-' in English also comes from the same Latin 'prae-' and appears in many English words like 'predict', 'prepare', and 'prevent', always carrying the sense of 'before' or 'in front'.
