* Anthro/Anthropo means "human" or "man."
* Philo means "love."
* -ism is a suffix indicating a belief, system, or practice.
Based on these roots, the word that most likely means "actions displaying a love for man" is "humanitarianism."
Humanitarianism is a belief system or practice focused on helping humanity and promoting human welfare. This aligns with the idea of actions displaying a love for man.
Here's why the other options aren't as fitting:
* Anthropology is the study of humans, not necessarily actions motivated by love.
* Philology is the study of language, not related to human love.
* Philosophy is a system of beliefs, not actions.
While philantrophy (love of humanity) shares the root "philo" and "anthro" it usually refers to charitable acts rather than a broader "actions displaying love."
