2.Articulation of consonants.


Consonant, any speech sound, such as that represented by t, g, f, or z, that is characterized by an articulation with a closure or narrowing of the vocal tract such that a complete or partial blockage of the flow of air is produced. Consonants are usually classified according to place of articulation (the location of the stricture made in the vocal tract, such as dental, bilabial, or velar), the manner of articulation (the way in which the obstruction of the airflow is accomplished, as in stops, fricatives, approximants, trills, taps, and laterals), and the presence or absence of voicing, nasalization, aspiration, or other phonation. For example, the sound for s is described as a voiceless alveolar fricative; the sound for m is a voiced bilabial nasal stop. Additional classificatory information may indicate whether the airstream powering the production of the consonant is from the lungs (the pulmonary airstream mechanism) or some other airstream mechanism and whether the flow of air is ingressive or egressive. The production of consonants may also involve secondary articulations—that is, articulations additional to the place and manner of articulation defining the primary stricture in the vocal tract.
Eighth letter of the alphabet. It corresponds to Semitic cheth and Greek eta (Η). It may derive from an early symbol for fence. In the early Greek alphabets a form with three horizontal bars and the simpler form H were both widely distributed. In Etruscan the prevailing form was similar to the early Greek form, and the same or a similar form occurs in very early Latin inscriptions, but the form H came into general use in Latin, either from the Chalcidic Greek alphabet of Cumae or from some other source. The modern majuscule H is derived directly from the Latin. The cursive Latin form resembled a stylized version of the modern minuscule h, as did the uncial form. Both of these forms result from writing the letter without taking the pen from the paper, the right-hand vertical bar being thus foreshortened and the horizontal stroke rounded. From these came the Carolingian form as well as the modern minuscule h.
In the alphabets used to write the East Ionic dialect of Greek the letter became superfluous as a result of the disappearance of the aspirate which it represented in that dialect. It was accordingly put to a new use to indicate the open long e which had arisen through alteration of the primitive Greek long a. In a few inscriptions from Thera, Naxos, and several other localities the letter was used with syllabic value; that is, it included he, thus showing its old consonantal and its new vocalic value at the same time. Eventually, as a result of the spread of the Ionic alphabet, its use for the long vowel e or η became general throughout Greece, while its consonantal value as the aspirate h passed from the western Greek alphabets into the Etruscan alphabets and then into the Latin and other alphabets of ancient Italy. In the Romance languages the sound has largely disappeared, but the letter is still extensively used, partly with only etymological value, (e.g., French homme), partly with fancied etymological value (e.g., French haut from Latin altus, with h through the influence of hoh, the Old High German word of the same meaning), partly with special orthographical functions. For example, in Italian h is used in combination with c or g to indicate the hard sound before a front vowel (e.g., chi, ghetto).
In English the initial h is pronounced in words of Germanic origin (e.g., hunt, hook); in some words of Romance origin, the h remains unpronounced (e.g., heir, honour), but in others it has been restored (e.g., humble, humour). The initial h often disappears in unaccented syllables (e.g., “What did he say?”). In chemistry H is the symbol for the element hydrogen.
