Here are some examples:
* Bibliophile: A lover of books
* Anglophile: A lover of England and English culture
* Sinophile: A lover of China and Chinese culture
* Musicophile: A lover of music
* Hydrophile: Something that attracts water (in chemistry)
The suffix "-phil" can also be used to indicate a person who studies a particular subject, like:
* Philosopher: A person who studies philosophy
* Ichthyophile: A person who studies fish
So, when you see "-phil" at the end of a word, it usually means that the word is referring to something that is loved, liked, or studied.
