Boss
Kingpin, Chief, Head
noun
Who is part parent to you? Your boss! They make it so you can take care of yourself by paying you, don't they? They'll break the legs of someone who crosses you. But they won't help you get back to sleep after you have nightmares. So they're only part like a parent.
This word consists of the kun'yomi reading for 親 and the on'yomi reading for 分. You've learned both of these so you should be able to read this already!
