O.

O (ō). 1. O, the fifteenth letter of the English alphabet, derives its form, value, and name from the Greek O, through the Latin. The letter came into the Greek from the Phœnician, which possibly derived it ultimately from the Egyptian. Etymologically, the letter o is most closely related to a, e, and u; as in E. bone, AS. bān; E. stone, AS. stān; E. broke, AS. brecan to break; E. bore, AS. beran to bear; E. dove, AS. dūfe; E. toft, tuft; tone, tune; number, F. nombre.

The letter o has several vowel sounds, the principal of which are its long sound, as in bone, its short sound, as in nod, and the sounds heard in the words orb, son, do (feod), and wolf (book). In connection with the other vowels it forms several digraphs and diphthongs. See Guide to Pronunciation, §§ 107-129.

2. Among the ancients, O was a mark of triple time, from the notion that the ternary, or number 3, is the most perfect of numbers, and properly expressed by a circle, the most perfect figure.

O was also anciently used to represent 11: with a dash over it (Ō), 11,000.

O (ō), n.; pl. O's or Oes (ōz). 1. The letter O, or its sound. "Mouthing out his hollow oes and aes." Tennyson.

2. Something shaped like the letter O; a circle or oval. "This wooden O [Globe Theater]". Shak.

3. A cipher; zero. [R.]

Thou art an O without a figure.
Shak.

O'. [Ir. o a descendant.] A prefix to Irish family names, which signifies grandson or descendant of, and is a character of dignity; as, O'Neil, O'Carrol.

O' (ō; unaccented &osl;), prep. A shortened form of of or on. "At the turning o' the tide." Shak.

O (ō), a. [See One.] One. [Obs.] Chaucer. "Alle thre but o God." Piers Plowman.

O (?), interj. An exclamation used in calling or directly addressing a person or personified object; also, as an emotional or impassioned exclamation expressing pain, grief, surprise, desire, fear, etc.

For ever, O Lord, thy word is settled in heaven.
Ps. cxix. 89.

O how love I thy law ! it is my meditation all the day.
Ps. cxix. 97.

&fist; O is frequently followed by an ellipsis and that, an in expressing a wish: "O [I wish] that Ishmael might live before thee !" Gen. xvii. 18; or in expressions of surprise, indignation, or regret: "O [it is sad] that such eyes should e'er meet other object !" Sheridan Knowles.

&fist; A distinction between the use of O and oh is insisted upon by some, namely, that O should be used only in direct address to a person or personified object, and should never be followed by the exclamation point, while Oh (or oh) should be used in exclamations where no direct appeal or address to an object is made, and may be followed by the exclamation point or not, according to the nature or construction of the sentence. Some insist that oh should be used only as an interjection expressing strong feeling. The form O, however, is, it seems, the one most commonly employed for both uses by modern writers and correctors for the press. "O, I am slain !" Shak. "O what a fair and ministering angel !" "O sweet angel !" Longfellow.

O for a kindling touch from that pure flame !
Wordsworth.

But she is in her grave, -- and oh
The difference to me !
Wordsworth.

Oh for a lodge in some vast wilderness !
Cowper.

We should distinguish between the sign of the vocative and the emotional interjection, writing O for the former, and oh for the latter.
Earle.

O dear, ∧ O dear me! [corrupted fr. F. O Dieu! or It. O Dio! O God! O Dio mio! O my God! Wyman.], exclamations expressive of various emotions, but usually promoted by surprise, consternation, grief, pain, etc.

2. (Metaph.) Of or pertaining to an object; contained in, or having the nature or position of, an object; outward; external; extrinsic; -- an epithet applied to whatever ir exterior to the mind, or which is simply an object of thought or feeling, and opposed to subjective.

In the Middle Ages, subject meant substance, and has this sense in Descartes and Spinoza: sometimes, also, in Reid. Subjective is used by William of Occam to denote that which exists independent of mind; objective, what is formed by the mind. This shows what is meant by realitas objectiva in Descartes. Kant and Fichte have inverted the meanings. Subject, with them, is the mind which knows; object, that which is known; subjective, the varying conditions of the knowing mind; objective, that which is in the constant nature of the thing known.
Trendelenburg.

Objective means that which belongs to, or proceeds from, the object known, and not from the subject knowing, and thus denotes what is real, in opposition to that which is ideal - - what exists in nature, in contrast to what exists merely in the thought of the individual.
Sir. W. Hamilton.

Objective has come to mean that which has independent exostence or authority, apart from our experience or thought. Thus, moral law is said to have objective authority, that is, authority belonging to itself, and not drawn from anything in our nature.
Calderwood (Fleming's Vocabulary).

3. (Gram.) Pertaining to, or designating, the case which follows a transitive verb or a preposition, being that case in which the direct object of the verb is placed. See Accusative, n.

&fist; The objective case is frequently used without a governing word, esp. in designations of time or space, where a preposition, as at, in, on, etc., may be supplied.

My troublous dream [on] this night make me sad.
Shak.

To write of victories [in or for] next year.

Objective line (Perspective), a line drawn on the geometrical plane which is represented or sought to be represented. -- Objective plane (Perspective), any plane in the horizontal plane that is represented. -- Objective point, the point or result to which the operations of an army are directed. By extension, the point or purpose to which anything, as a journey or an argument, is directed.

Syn. -- Objective, Subjective. Objective is applied to things exterior to the mind, and objects of its attention; subjective, to the operations of the mind itself. Hence, an objective motive is some outward thing awakening desire; a subjective motive is some internal feeling or propensity. Objective views are those governed by outward things; subjective views are produced or modified by internal feeling. Sir Walter Scott's poetry is chiefly objective; that of Wordsworth is eminently subjective.

In the philosophy of mind, subjective denotes what is to be referred to the thinking subject, the ego; objective what belongs to the object of thought, the non- ego.
Sir. W. Hamilton

Gen. xvi. 2.

Syn. -- To attain; gain; procure; acquire; win; earn. See Attain. -- To Obtain, Get, Gain, Earn, Acquire. The idea of getting is common to all these terms. We may, indeed, with only a slight change of sense, substitute get for either of them; as, to get or to gain a prize; to get or to obtain an employment; to get or to earn a living; to get or to acquire a language. To gain is to get by striving; and as this is often a part of our good fortune, the word gain is peculiarly applicable to whatever comes to us fortuitously. Thus, we gain a victory, we gain a cause, we gain an advantage, etc. To earn is to deserve by labor or service; as, to earn good wages; to earn a triumph. Unfortunately, one does not always get or obtain what he has earned. To obtain implies desire for possession, and some effort directed to the attainment of that which is not immediately within our reach. Whatever we thus seek and get, we obtain, whether by our own exertions or those of others; whether by good or bad means; whether permanently, or only for a time. Thus, a man obtains an employment; he obtains an answer to a letter, etc. To acquire is more limited and specific. We acquire what comes to us gradually in the regular exercise of our abilities, while we obtain what comes in any way, provided we desire it. Thus, we acquire knowledge, property, honor, reputation, etc. What we acquire becomes, to a great extent, permanently our own; as, to acquire a language; to acquire habits of industry, etc.

'oxy`s, from which it was supposed to be directly derived.] (Chem.) A binary compound of oxygen with an atom or radical, or a compound which is regarded as binary; as, iron oxide, ethyl oxide, nitrogen oxide, etc.

&fist; In the chemical nomenclature adopted by Guyton de Morveau, Lavoisier,and their associates, the term oxides was made to include all compounds of oxygen which had no acid (F. acide) properties, as contrasted with the acids, all of which were at that time supposed to contain oxygen. The orthography oxyde, oxyd, etc., was afterwards introduced in ignorance or disregard of the true etymology, but these forms are now obsolete in English. The spelling oxid is not common.

1. (Chem.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.96.

&fist; It occurs combined in immense quantities, forming eight ninths by weight of water, and probably one half by weight of the entire solid crust of the globe, being an ingredient of silica, the silicates, sulphates, carbonates, nitrates, etc. Oxygen combines with all elements (except fluorine), forming oxides, bases, oxyacid anhydrides, etc., the process in general being called oxidation, of which combustion is only an intense modification. At ordinary temperatures with most substances it is moderately active, but at higher temperatures it is one of the most violent and powerful chemical agents known. It is indispensable in respiration, and in general is the most universally active and efficient element. It may be prepared in the pure state by heating potassium chlorate.

This element (called dephlogisticated air by Priestley) was named oxygen by Lavoisier because he supposed it to be a constituent of all acids. This is not so in the case of a very few acids (as hydrochloric, hydrobromic, hydric sulphide, etc.), but these do contain elements analogous to oxygen in property and action. Moreover, the fact that most elements approach the nearer to acid qualities in proportion as they are combined with more oxygen, shows the great accuracy and breadth of Lavoisier's conception of its nature.
