Two constructions carry this sense. You can spare a person, or spare a person something: Railway Magazine in 1949 notes that visitors to postwar Germany are spared the sight of a devastated Cologne.

Note
Here the object is the thing held back, not the person shielded. The King James Bible of 1611 praises the man who "spareth his words," and in Milton's Paradise Lost (1667) the one addressed "didst not spare" the Father's dreadful thunder, meaning he unleashed it. The modern "spare me the lecture" joins both ideas. It asks for words to be withheld and for the listener to be spared them, as in the merciful sense.

UsageBowlers pick up or convert a spare.
Note
Its value is deferred: the frame's score cannot be finished until the next ball is rolled, because those pins are added to it. Only the second ball of a frame can make a spare, by clearing whatever the first left standing. Bowlers speak of converting a spare, and a tricky one is often judged by which pins remain.

Note
Shakespeare plays on both spares at once in Henry IV, Part 2: "give me the spare men, and spare me the great ones." The line sets the adjective for lean men beside a verb for leaving the great ones alone. The pun joins the adjective and the verb of mercy, which grew from distinct but probably related Old English words.

- 12To hold back from acting; to stop or refrain.
Similarrefrain, desist, forbear, relent, stop
Note
Old English sparian meant "to show mercy to, refrain from injuring or destroying," and the verb's mercy senses keep that core. Used with no object, spare simply means to hold back, and it is most natural in a negative: they would not spare. Its root is probably related to that of the "scant" adjective, and the two words share one spelling.

Moehringer, which looks back on "Heir versus Spare" as a family dynamic. The word carries the backup idea of the emergency-reserve adjective over to a person, and it stings.

Myanmar English gives the word a job: the spare is the extra hand who works aboard buses and lorries. In this use the noun names a person, so a spare on a bus means a worker riding along, not the spare tire in the boot. The context of the vehicle usually makes clear which one is meant.
