3. Growth and Decay.
Moreover, English, like all other languages, is subject to that constant growth and decay
that characterize all forms of life. It is a convenient figure of speech to speak of
languages as living and as dead. Although we rarely think of language as something that
possesses life apart from the people who speak it, as we can think of plants or of animals,
we can observe in speech something like the process of change that characterizes the life
of living things. When a language ceases to change, we call it a dead language. Classical
Latin is a dead language because it has not changed for nearly 2,000 years. The change
that is constantly going on in a living language can be most easily seen in the vocabulary.
Old words die out, new words are added, and existing words change their meaning. Much
of the vocabulary of Old English has been lost, and the development of new words to
meet new conditions is one of the most familiar phenomena of our language. Change of
meaning can be illustrated from any page of Shakespeare. Nice in Shakespeare’s day
meant foolish; rheumatism signified a cold in the head. Less familiar but no less real is
the change of pronunciation. A slow but steady alteration, especially in the vowel sounds,
has characterized English throughout its history. Old English stān has become our stone;
cū has become cow. Most of these changes are so regular as to be capable of
classification under what are called “sound laws.” Changes likewise occur in the
grammatical forms of a language. These may be the result of gradual phonetic
modification, or they may result from the desire for uniformity commonly felt where
similarity of function or use is involved. The person who says I knowed is only trying to
form the past tense of this verb after the pattern of the past tense of so many verbs in
English. This process is known as the operation of analogy, and it may affect the sound
and meaning as well as the form of words. Thus it will be part of our task to trace the
influences that are constantly at work, tending to alter a language from age to age as
spoken and written, and that have brought about such an extensive alteration in English
as to make the English language of 1000 quite unintelligible to English speakers of 2000.
