or¹ (ôr; ər when unstressed) Pronunciation Key
conj.

1. Used to indicate an alternative, usually only before the last term of a series: hot or cold; this, that, or the other.
2. Used to indicate the second of two alternatives, the first being preceded by either or whether: Your answer is either ingenious or wrong. I didn't know whether to laugh or cry.
3. Archaic Used to indicate the first of two alternatives, with the force of either or whether.
Used to indicate a synonymous or equivalent expression: acrophobia, or fear of great heights.
Used to indicate uncertainty or indefiniteness: two or three.

[Middle English, from other, or (from Old English, from oththe) and from outher (from Old English āhwæther, āther; see either).]

Usage Note: When all the elements in a series connected by or are singular, the verb they govern is singular: Tom or Jack is coming. Beer, ale, or wine is included in the charge. When all the elements are plural, the verb is plural. When the elements do not agree in number, some grammarians have suggested that the verb should agree in number with the nearest element: Tom or his sisters are coming. The girls or their brother is coming. Cold symptoms or headache is the usual first sign. Other grammarians, however, have argued that such constructions are inherently illogical and that the only solution is to revise the sentence to avoid the problem of agreement: Either Tom is coming or his sisters are. The usual first sign may be either cold symptoms or a headache. See Usage Notes at and/or, either, neither, nor¹.

Or·e·gon (ôr'ĭ-gən, -gŏn', ŏr'-) Pronunciation Key
Abbr. OR or Ore.
A state of the northwest United States in the Pacific Northwest. It was admitted as the 33rd state in 1859. Claimed by the United States after Capt. Robert Gray explored the mouth of the Columbia River in 1792, the area was further explored by Lewis and Clark in 1805 and was soon the site of fur-trading posts. The Oregon Country, a region encompassing all the land from the California border to Alaska and the Pacific Ocean to the Rocky Mountains, was held jointly by Great Britain and the United States from 1818 until 1846, when the international boundary was fixed at the 49th parallel. In 1848 the Oregon Territory was created, including all of present-day Washington and Idaho. The state's current boundaries were established in 1853. Salem is the capital and Portland the largest city. Population: 3,700,000.

or

c.1200, from O.E. conj. oþþe "either, or," related to O.N. eða, O.H.G. odar, Ger. oder, Goth. aiþþau "or." This was extended in early M.E. with an -r ending, perhaps by analogy of other "choice between alternative" words that ended this way (either, whether), then reduced to oþþr, at first in unstressed situations (commonly thus in Northern and Midlands Eng. by 1300), and finally reduced to or, though other survived in this sense until 16c. The contraction took place in the second term of an alternative, such as either ... or, a common construction in O.E., where both words originally were oþþe (see nor).

Or\, conj. [OE. or, outher, other, auther, either, or, AS. [=a]w?er, contr. from [=a]hw[ae]?er; [=a] aye + hw[ae]?er whether. See Aye, and Whether, and cf. Either.] A particle that marks an alternative; as, you may read or may write, -- that is, you may do one of the things at your pleasure, but not both. It corresponds to either. You may ride either to London or to Windsor. It often connects a series of words or propositions, presenting a choice of either; as, he may study law, or medicine, or divinity, or he may enter into trade.

If man's convenience, health, Or safety interfere, his rights and claims Are paramount. --Cowper.

Note: Or may be used to join as alternatives terms expressing unlike things or ideas (as, is the orange sour or sweet?), or different terms expressing the same thing or idea; as, this is a sphere, or globe.

Note: Or sometimes begins a sentence. In this case it expresses an alternative or subjoins a clause differing from the foregoing. "Or what man is there of you, who, if his son shall ask him for a loaf, will give him a stone?" --Matt. vii. 9 (Rev. Ver. ). Or for either is archaic or poetic.

Maugre thine heed, thou must for indigence Or steal, or beg, or borrow thy dispence. --Chaucer.
