The Silent K Rule in English
One of the most interesting pronunciation patterns in English is the silent K. When K is followed by N at the beginning of a word, the K is usually silent. This means you pronounce only the N sound.
- Know → /noʊ/
- Knife → /naɪf/
- Knight → /naɪt/
- Knot → /nɑːt/
This rule can help English learners improve pronunciation, spelling, and listening skills. It is also a useful pattern to remember when learning new K words.
