Origin of mine

1275–1325;1875–80for def 5; (v.) Middle Englishminen < Old Frenchminer (cognate with Provençal,Spanishminar,Italianminare) < Vulgar Latin*mīnāre, probably < a Celtic base *mein-; compare MIr méin,Welshmwyn ore, mineral; (noun) Middle English < Middle French, perhaps noun derivative of miner; compare Medieval Latinmina mine, mineral
Old English min "mine, my," (pronoun and adjective), from Proto-Germanic *minaz (cf. Old Frisian, Old Saxon Old High German min, Middle Dutch, Dutch mijn, German mein, Old Norse minn, Gothic meins "my, mine"), from the base of me. Superseded as adjective beginning 13c. by my.
n.1
"pit or tunnel in the earth for obtaining metals and minerals," c.1300, from Old French mine "vein, lode; tunnel, shaft; mineral ore; mine" (for coal, tin, etc,), of uncertain origin, probably from a Celtic source (cf. Welsh mwyn, Irish mein "ore, mine"), from Old Celtic *meini-. Italy and Greece were relatively poor in minerals, thus they did not contribute a word for this to English, but there was extensive mining from an early date in Celtic lands (Cornwall, etc.). From c.1400 as "a tunnel under fortifications to overthrow them."
v.2
"lay explosives," 1620s, in reference to old tactic of tunneling under enemy fortifications to blow them up; a specialized sense of mine (v.1) via a sense of "dig under foundations to undermine them" (late 14c.), and miner in this sense is attested from late 13c. Related: Mined; mining.
v.1
to dig, c.1300, "to tunnel under fortifications to overthrow them," from mine (n.1) or from Old French miner "to dig, mine; exterminate." From mid-14c. as "to dig in the earth" (for treasure, etc.). Figurative use from mid-14c. Related: Mined; mining.
12c. shortening of Old English ic, first person singular nominative pronoun, from Proto-Germanic *ekan (cf. Old Frisian ik, Old Norse ek, Norwegian eg, Danish jeg, Old High German ih, German ich, Gothic ik), from PIE *eg-, nominative form of the first person singular pronoun (cf. Sanskrit aham, Hittite uk, Latin ego (source of French Je), Greek ego, Russian ja, Lithuanian aš). Reduced to i by mid-12c. in northern England, it began to be capitalized mid-13c. to mark it as a distinct word and avoid misreading in handwritten manuscripts.
The reason for writing I is ... the orthographic habit in the middle ages of using a 'long i' (that is, j or I) whenever the letter was isolated or formed the last letter of a group; the numeral 'one' was written j or I (and three iij, etc.), just as much as the pronoun. [Otto Jespersen, "Growth and Structure of the English Language," p.233]
The form ich or ik, especially before vowels, lingered in northern England until c.1400 and survived in southern dialects until 18c. The dot on the "small" letter -i- began to appear in 11c. Latin manuscripts, to distinguish the letter from the stroke of another letter (such as -m- or -n-). Originally a diacritic, it was reduced to a dot with the introduction of Roman type fonts.
