1. The fourteenth letter and eleventh consonant in the English alphabet, having a corresponding place also in the alphabets from which ours comes. The comparative scheme of forms in these alphabets and in the Egyptian (see A) is as follows:
2. The value of the character has been the same through the whole history of its use. It stands for the “dental” nasal, the nasal sound corresponding to d and t, as does m to b and p, and ng to g and k. This sound, namely, implies for its formation the same check or mute-contact as d and t, with sonant vibration of the vocal cords as in d, and further with unclosure of the passage from the mouth into the nose, and nasal resonance there. Among the nasals, it is by far the most common in English pronunciation (more than twice as common as m, and eight times as common as ng). While all the nasals are semivocalic or liquid, n is the only one which (like l, but not more than half as often) is used with vocalic value in syllable-making: namely, in unaccented syllables, where an accompanying vowel, formerly uttered, is now silenced: examples are token, rotten, open, lesson, reason, oven; such form, on an average, about one in eight hundred of English syllables. The sign n has no variety of sounds; but before ch, j, in the same syllable (as in inch, hinge) it takes on a slightly modified—a palatalized—character; and similarly it is gutturalized, or pronounced as ng, before k and g (hard), as in ink, finger; and its digraph ng (see G) is the usual representative of the guttural or back-palatal nasal, which in none of our alphabets has a letter to itself. N is doubled under the same circumstances as other consonants, and in a few words (as kiln, damn, hymn) is silent. In the phonetic history of our family of languages, n is on the whole a constant sound; that is to say, there is no other sound into which it passes on a large scale; but its loss, with accompanying vowel-modification, has been a frequent process.

1. the fourteenth letter of English alphabet, is a vocal consonent, and, in allusion to its mode of formation, is called the dentinasal or linguanasal consonent. Its commoner sound is that heard in ran, done; but when immediately followed in the same word by the sound of g hard or k (as in single, sink, conquer), it usually represents the same sound as the digraph ng in sing, bring, etc. This is a simple but related sound, and is called the gutturo-nasal consonent. See guide to pronunciation, §§ 243-246.
2. n. (Print.) A measure of space equal to half an M (or em); an en.
