The silent letter T appears in many common English words, but it isn’t pronounced even though it’s still written. Learning when the T is silent—like in “listen,” “castle,” and “often”—helps English learners speak more naturally and avoid pronunciation mistakes. Understanding silent T rules is an easy way to improve fluency and sound more like a native speaker.
What Is a Silent Letter T?
A silent T is when the letter T appears in a word but is not pronounced. You still write the word with a “T,” but you do not say the /t/ sound when speaking.
For example:
-
castle → /ˈkæsəl/ (not /ˈkæstəl/)
-
listen → /ˈlɪsən/ (not /ˈlɪstən/)
-
often → /ˈɒfən/ or /ˈɔːfən/ (not /ˈɒftən/)
This means that the T is silent, even though you see it in writing. Knowing when to ignore the T sound will help your pronunciation become smoother and more natural.
