Where does mine come from?
The possessive “mine” developed from Old English “mīn,” the genitive form of the first-person singular pronoun, a grammatical pattern that remains in use today. The mining verb entered English through Old French “miner,” related to the Latin “mina,” a unit or place associated with extracting metals, and developed into the family of forms “miner,” “mined,” and “mining.” The related English word “mineral” also reflects this mining tradition.
