So, when you see "-phone" at the end of a word, it usually refers to something related to sound or the transmission of sound.
Here are some examples:
* Telephone: A device used to transmit sound over a distance.
* Microphone: A device that converts sound waves into electrical signals.
* Homophone: Words that sound the same but have different meanings and spellings (e.g., "to," "too," and "two").
* Symphonic: Relating to a symphony, a large musical composition for an orchestra.
* Phonograph: A device that records and plays back sound.
