mine: English has two quite distinct words mine. The first person possessive pronoun [OE] goes back to a prehistoric Germanic *mīnaz (source also of German mein, Dutch mijn, and Swedish and Danish min), which was derived from the same Indo-European source as produced English me. Originally it was an adjective, but in the 13th century the -n was dropped before consonants, and eventually the resulting my took over the adjective slot altogether, leaving mine as a pronoun only. Mine ‘excavation’ [14] is of uncertain origin.

It comes via Old French from an assumed Vulgar Latin *mina, which may go back ultimately to a Celtic *meini- ‘ore’ (Gaelic has mein ‘ore, mine’ and Welsh mwyn ‘ore’). The use of the word for an ‘explosive device’, which dates from the 17th century, arose from the practice of digging tunnels or ‘mines’ beneath enemy positions and then blowing them up.

Trojan priest of Apollo, from Latin Laocoon, from Greek Laukoun, from laos "people" (see lay (adj.)) + koeo "I mark, perceive."
Laocoön, n. A famous piece of antique sculpture representing a priest of that time and his two sons in the folds of two enormous serpents. The skill and diligence with which the old man and lads support the serpents and keep them up in their work have been justly regarded as one of the noblest artistic illustrations of the mastery of human intelligence over brute inertia.
