In a large class of words, as a consequence of a series of historical sound changes, including the Great Vowel Shift, the presence of a suffix on the end of a word influenced the development of the preceding vowel, and in a smaller number of cases it affected the pronunciation of a preceding consonant. When the inflection disappeared in speech, but remained as a historical remnant in the spelling, this silent was reinterpreted synchronically as a marker of the surviving sounds.
