What are some word with the silent ng and nk?

You're thinking of the silent "g" and "k" at the end of words. Here are some examples:

Silent "g":

* Sign: The "g" is silent in "sign."

* Campaign: The "g" is silent in "campaign."

* Foreign: The "g" is silent in "foreign."

* Design: The "g" is silent in "design."

* Reign: The "g" is silent in "reign."

Silent "k":

* Knife: The "k" is silent in "knife."

* Knee: The "k" is silent in "knee."

* Know: The "k" is silent in "know."

* Knock: The "k" is silent in "knock."

* Kneel: The "k" is silent in "kneel."

It's important to note that while the letters are silent, they still influence the pronunciation of the preceding vowel. For example, the "i" in "sign" has a different sound than the "i" in "sin" because of the silent "g."
