- It thus appears that the belief, not uncommonly held, that O represents, and is imitated from, the rounded position of the lips in its utterance, is a delusion. The historical value of the letter (as already noticed) is that of our o, in note, etc., whether of both long and short quantities, as in Latin and the earliest Greek, or of short only, as in Greek after the addition to that alphabet of a special sign for long o (namely omega,
Ω, ω). This vowel-sound, the name-sound of o, is found in English usage only with long quantity in accented syllables. There is no closely corresponding short vowel in standard English, but only in dialectal pronunciation, as in the New England utterance of certain words (much varying in number in different individuals): for example, home, whole, none. What we call “short o” (in not, on, etc.) is a sound of altogether different quality, very near to a true short ä (that is, a short utterance corresponding to the a of arm, father), but verging slightly toward the “broad” a (â) or o (ô) of laud, lord. “Short o” has a marked tendency to take on a “broader” sound, especially before r, and especially in America: hence the use, in the respellings of this work, of ô, which varies in different mouths from the full sound of â to that of ŏ. After these three values of the character, the next most common one is that of the oo-sonnd, the original and proper sound of u (represented in this work by ö), as in move, with the nearly corresponding short sound (marked u) in a few words, as wolf, woman. All these vowel-sounds partake of what is usually called a “labial” or a “rounded” character: that is to say, there is involved in their utterance a rounding and closing movement of the lips (and, it is held, of the whole mouth-cavity), in different degrees — least of all in ŏ, more and more in â, ō, u, ö; in the last, carried to its extreme, no closer rounding and approximation being possible. The labial action helps to give the vowel-sounds in question their fully distinctive character; but it can be more or less slighted without leaving them unrecognizable, and, in the generally indifferent habit of English pronunciation, is in a degree neglected, even in accented syllables, and yet more in unaccented. Our “long ō,” it should be added, regularly ends with a vanishing sound of oo (ö), as our ā with one of ē. O also has in many words the value of the “neutral” vowels of hut, hurt: for example, in son, come, love, work. O is further a member of several very common and important digraphs: thus, oo, the most marked representative of the ö-sound (in moon, rood, etc.), but also pronounced as u (book, look, etc.) and ŭ (blood, etc.); ou (in certain situations ow), oftenest representing a real diphthong (in out, sound, now, etc.), but also a variety of other sounds (as in through, could, ought, rough); oi (in certain situations oy), standing for a real diphthongal sound of which the first element is the “broad” o- or a-sound (for example, point, boy); oa (load, etc.), having the “long” o-sound; others, as eo (variously pronounced, as in people, yeoman, jeopard), oe (in foe, does, etc.), are comparatively rare.

- 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.
- 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.
- interjection 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.
- interjection exclamations expressive of various emotions, but usually promoted by surprise, consternation, grief, pain, etc.

Without referring to geometry we can see at a glance by Fig. 172, where we have simply turned the square _o o o o_ on its centre so that its angles touch the sides of the outer square, that it is exactly half of square _ABEF_, since each quarter of it, such as
By drawing _ff_, _f·f_ passing through the diagonals we get the four points _o o o o_ through which to draw the smaller square.

It was strange to hear the pipes of the Highlanders skirl shrilly through old Boulogne, and to catch the sound of English voices in the clarion notes of the "Marseillaise," but, strangest of all to French ears, to listen to that new battle-cry, "Are we down-hearted?" followed by the unanswerable "No -- o-- o!" of every regiment.
"So -- o-- o are we," gasped Grace, staggering to her feet, and almost instantly landing on her back on the ground where the wind had hurled her.
