* No Comprehensive List: There isn't a definitive list of all words in the English language, especially considering the constant evolution of language.
* Subjectivity: Some letters might be considered "silent" depending on the dialect or pronunciation. For example, the "h" in "honor" is often silent in American English but pronounced in British English.
* Contextual Silence: Some letters are only silent in certain words. The "e" at the end of a word might be silent but can affect the pronunciation of the preceding vowel.
Examples of Words with Silent Letters:
* "k" in "knife"
* "g" in "gnat"
* "b" in "debt"
* "h" in "hour"
* "e" in "write"
Instead of focusing on an exact number, it's more important to understand the concept of silent letters and how they affect pronunciation.
