word: O
definition:
O

O
(&omacr)
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.

definition:
O

O
(&omacr)
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.

&hand_; 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.

&hand_; 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!

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

word: Objective
definition:
Objective

Ob*jec"tive
(&obreve_;b*jĕk"tĭv)
a.
[Cf. F. objectif.]
1.
Of or pertaining to an object.

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 is exterior to the mind, or which is simply an object of thought or feeling, as opposed to being related to thoughts of feelings, 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 has come to mean that which has independent existence 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.
Hence:
Unbiased; unprejudiced; fair; uninfluenced by personal feelings or personal interests; considering only the facts of a situation unrelated to the observer; -- of judgments, opinions, evaluations, conclusions, reasoning processes.

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.

4.
(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.

&hand_; 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 doth make me sad.
Shak.

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

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.

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

word: octothorpe
definition:
octothorpe

octothorp

oc"to*thorp, oc"to*thorpe
n.
[octo- eight + thorp Etymology of thorp uncertain.  (ca. 1965). See quotes below.  Possibly derived from octalthorpe or octotherp (once used by the Bell System?).]
A typographic symbol (#) having two vertical lines intersected by two horizontal lines.  It is also called the crosshatch, hash, numeral sign and number sign; in the U. S. it is commonly called the pound sign, especially to designate the symbol as used on digital telephone dials, but this can be confusing to Europeans who think of the pound sign as the symbol for the British pound.  It is commonly used as a symbol for the word number; as in #36 (meaning: number thirty-six).

For the following explanation, I am indebted to Michael Quinion, whose World Wide Words web site (www.quinion.com/words) is a fascinating and invaluable resource for anyone interested in words and their origins.
   Anyone who has ever used a touch-tone telephone has seen the octothorpe. It's that little tic-tac-toe symbol in the lower right corner of the keypad, right across from the asterisk (which the telco folks, in their infinite wisdom, insist on calling a "star"). According to a Bell Laboratories engineer named Ralph Carlsen, the octothorpe and asterisk keys were developed in the early 1960s and originally intended to be used only to access computer systems via a telephone line. The octothorpe symbol itself had already existed for many years, although it was usually called a "pound sign" or "number sign" because it was often used in commerce to designate weight or quantity.
   According to Ralph Carlsen, a fellow Bell Labs engineer named Don MacPherson invented the term "octothorpe" when faced with the task of explaining the new touch-tone phones to corporate users. MacPherson chose "octo" (Latin for "eight") because there were eight points on the symbol.
   "Thorpe" is indeed an Old Norse word meaning "village," often found in the names of English towns, but that was evidently not the source in this case. According to Carlsen, "thorpe" was chosen because at the time MacPherson was involved in a campaign pressing for the return of legendary athlete Jim Thorpe's Olympic medals from Sweden..

Word Detective (http://www.word-detective.com/072999.html#octothorpe [accessed 20090708]

octothorp
    Otherwise known as the numeral sign.  It has also been used as
    a symbol for the pound avoirdupois, but this usage is now
    archaic.  In cartography, it is also a symbol for village: eight
    fields around a central square, and this is the source of its
    name.  Octothorp means eight fields.

word: Oil
definition:
Oil

Oil
(oil)
n.
[OE. oile, OF. oile, F. huile, fr. L. oleum; akin to Gr. _;.  Cf. Olive.]
Any one of a great variety of unctuous combustible substances, more viscous than and not miscible with water; as, olive oil, whale oil, rock oil, etc.  They are of animal, vegetable, or mineral origin and of varied composition, and they are variously used for food, for solvents, for anointing, lubrication, illumination, etc.  By extension, any substance of an oily consistency; as, oil of vitriol.

&hand_; The mineral oils are varieties of petroleum.  See Petroleum.  The vegetable oils are of two classes, essential oils (see under Essential), and natural oils which in general resemble the animal oils and fats.  Most of the natural oils and the animal oils and fats consist of ethereal salts of glycerin, with a large number of organic acids, principally stearic, oleic, and palmitic, forming respectively stearin, olein, and palmitin.  Stearin and palmitin prevail in the solid oils and fats, and olein in the liquid oils.  Mutton tallow, beef tallow, and lard are rich in stearin, human fat and palm oil in palmitin, and sperm and cod-liver oils in olein.  In making soaps, the acids leave the glycerin and unite with the soda or potash.

2.
(Computers)
A systematic arrangement of all of the important categories of objects or concepts which exist in some field of discourse, showing the relations between them.  When complete, an ontology is a categorization of all of the concepts in some field of knowledge, including the objects and all of the properties, relations, and functions needed to define the objects and specify their actions.  A simplified ontology may contain only a hierarchical classification (a taxonomy) showing the type subsumption relations between concepts in the field of discourse.  An ontology may be visualized as an abstract graph with nodes and labeled arcs representing the objects and relations.
The concepts included in an ontology and the hierarchical ordering will be to a certain extent arbitrary, depending upon the purpose for which the ontology is created.  This arises from the fact that objects are of varying importance for different purposes, and different properties of objects may be chosen as the criteria by which objects are classified.  In addition, different degrees of aggregation of concepts may be used, and distinctions of importance for one purpose may be of no concern for a different purpose.
