a.
Uttered by the aid of the palate; -- said of certain sounds, as the sound of k in kirk.
n.
A sound produced by an explosive impulse of the breath; (Phonetics) one of consonants p, b, t, d, k, g, which are sounded with a sort of explosive power of voice. [See Guide to Pronunciation, Ã 155-7, 184.]
n.
A sound uttered, or a letter pronounced, by the aid of the palate, as the letters k and y.
n.
A tree or wood of the Bible (2 Chron. ii. 8; 1 K. x. 11).
a.
Having the place of articulation on the soft palate; guttural; as, the velar consonants, such as k and hard q.
n.
One of the sonant mutes /, /, / (b, d, g), in Greek, or of their equivalents in other languages, so named as intermediate between the tenues, /, /, / (p, t, k), and the aspiratae (aspirates) /, /, / (ph or f, th, ch). Also called middle mute, or medial, and sometimes soft mute.
n.
A letter which represents no sound; a silent letter; also, a close articulation; an element of speech formed by a position of the mouth organs which stops the passage of the breath; as, p, b, d, k, t.
superl.
Uttered in a whisper, or with the breath alone, without voice, as certain consonants, such as p, k, t, f; surd; nonvocal; aspirated.
n.
The acetabulum. See Acetabulum, 2. Q () the seventeenth letter of the English alphabet, has but one sound (that of k), and is always followed by u, the two letters together being sounded like kw, except in some words in which the u is silent. See Guide to Pronunciation, / 249. Q is not found in Anglo-Saxon, cw being used instead of qu; as in cwic, quick; cwen, queen. The name (k/) is from the French ku, which is from the Latin name of the same letter; its form is from the Latin, which derived it, through a Greek alphabet, from the Ph/nician, the ultimate origin being Egyptian.
n.
A genus of spreading shrubs with many stems, from one species of which (K. triandra), found in Peru, rhatany root, used as a medicine, is obtained.
n.
A native or inhabitant of Byzantium, now Constantinople; sometimes, applied to an inhabitant of the modern city of Constantinople. C () C is the third letter of the English alphabet. It is from the Latin letter C, which in old Latin represented the sounds of k, and g (in go); its original value being the latter. In Anglo-Saxon words, or Old English before the Norman Conquest, it always has the sound of k. The Latin C was the same letter as the Greek /, /, and came from the Greek alphabet. The Greeks got it from the Ph/nicians. The English name of C is from the Latin name ce, and was derived, probably, through the French. Etymologically C is related to g, h, k, q, s (and other sibilant sounds). Examples of these relations are in L. acutus, E. acute, ague; E. acrid, eager, vinegar; L. cornu, E. horn; E. cat, kitten; E. coy, quiet; L. circare, OF. cerchier, E. search.
v. t.
To form or be at the end of; as, the letter k ends the word back.
superl.
Belonging to the class of sonant elements as distinguished from the surd, and considered as involving less force in utterance; as, b, d, g, z, v, etc., in contrast with p, t, k, s, f, etc.
n. pl.
A class of levelers in the time of K. Henry I.
n.
Any one of the lene consonants, as p, k, or t (or Gr. /, /, /).
a.
Having the anterior toes joined only part way down with a web; half-webbed; as, a semipalmate bird or foot. See Illust. k under Aves.
a.
Formed by complete closure of the mouth passage, and with the nose passage remaining closed; stopped, as are the mute consonants, p, t, k, b, d, and hard g.
a.
Applied to certain mute consonants, as p, k, and t (or Gr. /, /, /).
a.
See Gimmal. K () the eleventh letter of the English alphabet, is nonvocal consonant. The form and sound of the letter K are from the Latin, which used the letter but little except in the early period of the language. It came into the Latin from the Greek, which received it from a Phoenician source, the ultimate origin probably being Egyptian. Etymologically K is most nearly related to c, g, h (which see).
n.
An Alkali element, occurring abundantly but always combined, as in the chloride, sulphate, carbonate, or silicate, in the minerals sylvite, kainite, orthoclase, muscovite, etc. Atomic weight 39.0. Symbol K (Kalium).
