Foremost, the aphorism is gotten from "aphorismosis," a Greek word which means a phrase that is concise but contains a general truth. This phrase is gotten from the word "horizon," and it means "I determine" or " I define." Hence, aphorism can be said to be a phrase that gives a particular definition to some aspects of life. Conversely, the proverb is gotten from the Latin word "proverbium."
This is also the combination of three different terms -pro-verb-ium. Pro means "for," the verb means "word," while the suffix "ium" denotes the word as a noun or referring to a particular description. Hence, combining the meanings of these broken words, the proverb can simply mean using a word or phrase to describe a particular situation.
The aphorism, now, can be said to be a concise phrase that describes some principles or thought concepts. Meanwhile, the proverb is also a phrase that explains a fundamental truth that can be applied to a particular situation. Proverbs are usually credited to the ancestors or the elders, while aphorism happens to be a form of quotes credited to successful people.
