Interesting Fact: Quill

What word can mean both a spike on a porcupine and a bird feather used as a pen?

Final answer:

Answer:

The word that starts with the letter 'Q' and can mean both a spike on a porcupine and a bird feather used as a pen is 'quill'.

Explanation:

The word that starts with the letter 'Q' and can mean both a spike on a porcupine and a bird feather used as a pen is quill. A quill is a stiff, pointed structure on the back of a porcupine or a large feather that was used as a writing instrument in the past.

A quill is the sharp, pointy spike on a porcupine's body. It serves as a defense mechanism to protect the porcupine from predators.

On the other hand, a quill is also a bird feather that has been treated and shaped to be used as a pen. In the past, quills were commonly used as writing instruments before the invention of the modern pen. People would dip the quill in ink and use it to write or draw.

So, "quill" is the word that can have both meanings: a spike on a porcupine and a bird feather used as a pen.
