☞ Of may be used in a subjective or an objective sense. “The love of God” may mean, our love for God, or God's love for us.

☞ From is the primary sense of this preposition; a sense retained in off, the same word differently written for distinction. But this radical sense disappears in most of its application; as, a man of genius; a man of rare endowments; a fossil of a red color, or of an hexagonal figure; he lost all hope of relief; an affair of the cabinet; he is a man of decayed fortune; what is the price of corn? In these and similar phrases, of denotes property or possession, or a relation of some sort involving connection. These applications, however all proceeded from the same primary sense. That which proceeds from, or is produced by, a person or thing, either has had, or still has, a close connection with the same; and hence the word was applied to cases of mere connection, not involving at all the idea of separation.
