The Spanish verb 'realizar' (meaning 'to make real' or 'to realize') comes from Latin roots. It starts with the Latin word 'res' meaning 'thing' or 'matter'. When combined with the Latin adjective suffix '-alis', it formed 'realis' meaning 'real' or 'relating to things'. Finally, the addition of the verb-forming suffix '-izare' (which came from Greek '-izein') created the verb 'realizar', literally meaning 'to make real'.

This etymology helps explain why 'realizar' is used both in the sense of 'to carry out/accomplish' (making something real or actual) and 'to realize' (making something real in one's mind).

Some related Spanish words include 'real' (real, actual) and 'realidad' (reality), which come directly from the same Latin root 'realis'. When you see these words together, you can understand how 'realizar' essentially means to bring something into 'realidad' or to make it 'real'.

English speakers can easily connect 'realizar' to words like 'real', 'reality', and 'realize', which share the same Latin ancestry. The English word 'realize' follows almost the exact same formation pattern as Spanish 'realizar': both take the Latin 'realis' and add a verb-forming suffix. This explains why both words share similar meanings of both 'to make real' and 'to become aware of'.
