More Silent Letters-article #2 in series

Why does English have so many silent letters and rule exceptions?  Most reasons for silent letters in English relate to the origins of the word.  For example, the word “knight” has two silent sounds-K and GH.  This word originated from the German word for servant, “knecht” in which each letter is pronounced.  English has many words that end in a silent E that changes the prior vowel sound.  Such as the word “hate” in which the final silent E makes the prior vowel A long.  Some of these words with the silent final E,  originated from the time of Chaucer when the final E was pronounced and, therefore made words such as “bite” a two syllable word.   The word “bite” was pronounced as “ bi  te” with the final E pronounced with the long E sound.  English speakers must memorize these unique word spellings and pronunciations or regularly use online dictionaries.
