favor

The word "favor" has two main sides. First, as a noun, it means an act of kindness or a helpful service. "She did me a huge favor by watching my dog while I was on vacation." In this sense, it usually means someone is willing to take a little time or effort to help another person. Asking for a favor is not a demand; it is a request, and it often carries the feeling that you are asking someone to go a little out of their way.

Second, as a verb, "to favor" means to prefer or support one thing over another. You might say, "I favor dark chocolate over milk chocolate," or "The coach favors a defensive strategy." This meaning can also suggest unfair preference, as when a teacher clearly favors one student over the others. In another common use, "to favor" can mean to protect an injured part of the body, as in "favoring" a sore leg while walking. In some contexts, it can also mean to look like a family member, as in "he favors his father."

Historically, "favor" came through Old French and was connected with approval, support, and goodwill. That older sense still lives on in phrases like "in favor of," which means supporting something, and "in someone's favor," which means to someone's advantage. Whether you are asking for help, showing support for an idea, noticing unfair preference, or describing a family likeness, "favor" is a word that moves easily between kindness, support, and preference in everyday English.
