anthropo

The root anthropo- comes from Greek anthrōpos, meaning "human being, person" — not man as opposed to woman, but the human being as a species, set apart from gods and animals. The Greeks used it to talk about humankind as a whole, and that scholarly, big-picture flavor still clings to every word built on it: anthropo- words almost always sound academic, never casual.

The clearest member of the family is anthropology — anthrōpos (human) + logos (study) = "the study of humans." It is exactly what the parts say: a science that looks at people, their origins, their bodies, and their cultures. Add the agent suffix and you get anthropologist, the person who does that studying.

The second branch comes from putting anthrōpos together with phil- (love). Greek philanthrōpia meant "love of humankind" — goodwill toward all people. English borrowed it as philanthropy, and over the centuries narrowed it to its most visible form: rich donors funding schools, hospitals, and foundations. The adjective philanthropic describes that charitable spirit. So the logic chain is simple: love (phil) + humans (anthropos) = caring for humanity = charity.

A third branch describes things that merely look human. Add the suffix -oid ("resembling, like") and you get anthropoid — "human-like." It is used both as an adjective (an anthropoid posture) and as a noun for the great apes that most resemble us. Same idea drives anthropomorphic (anthropo- + morph shape = "human-shaped"), used when we give human form or feelings to animals, gods, or robots.

There is also a darker member. Swap love for hatred and you get misanthrope (misos hate + anthrōpos human) — someone who dislikes people in general. (Neither anthropomorphic nor misanthrope is in this word set, but they show the same building blocks at work.)

The pattern to remember: anthropo- always plants "human" at the center, and the surrounding piece tells you what we are doing with humans — studying them (anthropology), loving them (philanthropy), or resembling them (anthropoid).
