v1.c6.2

§ 48. By single consonants are implied those consonants which stand alone in a word, and which being in a measure unsupported are subjected to many and various changes. These changes may conveniently be considered under two classes. First, those whose operation varies with the position of the letter in a word, which are therefore called positional changes; and, secondly, those whose operation is not influenced by position, and which, being chiefly changes from one organ of speech to another, will be called organic changes.
