There are so many examples of prepositions in English language. Both 'Of' and 'For' are two most important examples of preposition. The simple truth about these words is that, they appear more often than some words in any write-up. And without them, whatever point you might be making will be completely useless. However, there are some differences between 'Of' and 'For'. These differences are basically in terms of what the two words are used for. 'Of' is used for so many things in a sentence.
It means away from and it shows the relationship between an object and the rest of the sentence. For example: Of all the companies in this country, you are the best. Another example is, United States is one of the most beautiful countries in the world. 'For' is also a preposition which serves most important functions of a preposition. For example: They were stoned for several hours. It can be used as conjunction. For example: He lost his car, for he got into trouble.
Two of the most commonly used prepositions, which are “of,” and “for,” represent a part of speech that like all prepositions indicates a relationship between an object in a sentence. The word “of” is already considered to be an old English preposition, which means away, or away from something. The preposition “for,” on the other hand, initially came from before, which also means “on account of.” The word “of” is a proposition that may say relating to or about, and it may also be used for distance, source, and reason.
It merely signifies the relationship between the objects, “for,” on the other hand, refers to meaning over hours, years, and days. It may also be utilized as a proposition of distance and purpose. Both words are commonly used as prepositions that link subjects or objects together in a sentence. The word “of” can is used in a general or broader sense while for is specific. “For,” is the preposition used for distance, time, and purpose sentence
