You can reason with a bull dog, astonish a bull, fascinate a boa, frighten a tiger, soften a lion; no resource with such a monster as a loose cannon. You cannot kill it, it is dead; and at the same time it lives. It lives with a sinister life which comes from the infinite.

The Germanic word is from PIE *leus-, an extended form of root *leu- "to loosen, divide, cut apart."

The verb also is merged with, or has taken the (weaker) sense of, the related Middle English leese "be deprived of, lose" (Old English leosan, a class II strong verb whose past participle loren survives in forlorn and lovelorn), from Proto-Germanic *leusanan (source also of Old High German virliosan, German verlieren, Old Frisian urliasa, Gothic fraliusan "to lose").

loss (n.)
Old English los "ruin, destruction," from Proto-Germanic *lausa- (from PIE root *leu- "to loosen, divide, cut apart"), with an etymological sense of "dissolution."

Phrase at a loss "confused, uncertain" (1590s) is a phrase from hunting, in reference to hounds losing the scent. To cut (one's) losses is from 1885, originally in finance.

lot (n.)
Old English hlot "object used to determine someone's share" (anything from dice to straw, but often a chip of wood with a name inscribed on it), also "what falls to a person by lot," from Proto-Germanic *khlutom (source also of Old Norse hlutr "lot, share," Old Frisian hlot "lot," Old Saxon hlot, Middle Dutch, Dutch lot, Old High German hluz "share of land," German Los), from a strong verb (the source of Old English hleotan "to cast lots, obtain by lot; to foretell"). The whole group is of unknown origin.

The object was placed with others in a receptacle (such as a hat or helmet), which was shaken, the winner being the one whose name or mark was on the lot that fell out first. Hence the expression cast lots; to cast (one's) lot with another (1530s, originally biblical) is to agree to share winnings. In some cases the lots were drawn by hand, hence to draw lots. The word was adopted from Germanic into the Romanic languages (Spanish lote, and compare lottery, lotto).

The common U.S. city lot was a rectangle 25 feet wide (along the street) by 100 deep; it was so universal as to be sometimes a unit of measure.

Meaning "group, collection" is 1725, from the notion of auction lots. Lots in the generalized sense of "great many" is attested by 1812; lotsa, colloquial for "lots of," is from 1927; lotta for "lot of" is by 1906.
