It is in generally agreed the written form of a natural language is the 1.______
written record of the oral form. Naturally the written form should agree to 2.______
the oral form. This is fairly true of English in its earlier stage, i.e. Old 3.______
English. The speech of the time was represented very much faithfully in 4.______
writing than it is today. With the development of the language, more and
more differences occur between the two. The external reason for this is that 5.______
the English alphabet was adopted from Romans, which does not have a 6.______
separate letter to represent each sound in the language so as that some letters 7.______
must do double duty or work together in combination.
Another reason is as the pronunciation has changed more rapidly than 8.______
spelling over the years, and in some cases the two have drawn far away. 9.______
During the last five hundred years, though the sounds of speech have
changed considerably, there have been no corresponding changes of
spelling. Furthermore, while English borrowed words from other 10.______
languages, it borrowed spelling as well. The early borrowings were
assimilated and the later ones, however, do not conform to the rules of
English pronunciation and spelling.
