It's often found in English words like:
* Amorous: full of or expressing love or passion
* Amatory: relating to or expressing love
* Amicable: friendly, peaceful, and agreeable
* Amateur: a person who engages in a pursuit, especially a sport, on an unpaid basis
* Amity: friendly relations, especially between countries
It's important to note that "amo" is a root word and not a complete word on its own. It's combined with other prefixes and suffixes to form new words with different meanings.
