Choose the word in which the underlined letter is silent: knee, sit, top, run.

## The reasoning This question tests your knowledge of **silent letters** — letters written but not pronounced. Let's examine each word's pronunciation: - **knee** → sounds like "nee" (the 'k' is silent) - **sit** → sounds like "sit" (all letters pronounced) - **top** → sounds like "top" (all letters pronounced) - **run** → sounds like "run" (all letters pronounced) The word **knee** has a silent 'k'. When 'k' appears before 'n' at the start of English words (like knife, knight, knock, know), the 'k' is never pronounced. You just say the 'n' sound. ## Why the wrong options tempt you The other words (sit, top, run) are simple phonetic words where every letter makes its expected sound. If you're rushing or don't know about silent letter patterns, you might think all letters in all these words are pronounced. ## Quick takeaway **Remember the "kn-" pattern:** When you see 'k' before 'n' at the beginning of a word (knife, know, kneel, knight), the 'k' is always silent — just say the 'n' sound!
