Usage: 元気(げんき) covers two things English keeps apart — being in good health and having energy and spirits — and context decides which is meant. Said of someone recovering, it is health; said of a 子供(こども) tearing around the room, it is liveliness.

  • 健康(けんこう) is the medical word: it describes the state of the body, and is what a checkup reports. 元気(げんき) describes how someone seems — visibly well, cheerful, full of energy. A person can be 健康(けんこう) but not 元気(げんき) if they are simply low.
  • As a noun it names the energy itself: 元気(げんき)ない, 元気(げんき)().

Forms

  • 元気(げんき) + noun: energetic, lively
  • 元気(げんき) / 元気(げんき)です: is well (predicate)
  • 元気(げんき): energetically (adverbial)

Common expressions

  • 元気(げんき)です: How have you been? Note that this is **not** a daily greeting. It asks after someone you have not seen for a while, so it pairs naturally with (ひさ)しぶり and sounds strange said to a colleague every morning.
  • 元気(げんき)? / 元気(げんき)だった? : the casual version, between friends.
  • 元気(げんき)ない: low, out of sorts, off form
  • 元気(げんき)(): cheer up, pull yourself together (元気(げんき)づける is what you do to someone else)
  • 元気(げんき)なる: get better, recover

Register: adding お makes it polite. お元気(げんき) as a parting line means "take care of yourself" and suits a long separation rather than a see-you-tomorrow.
