To Bring Up, To Raise, To Cultivate
transitive verb, ichidan verb
This is similar to 育つ, except now you're doing the raising of someone. This word means to bring up or to raise. You can remember this because of the てる. Your version of bringing a child up involves tearing (てる) all their clothes to make them look poor so they can get the cheaper lunch at school. You're rich because of all the tax breaks you get from all the children you're raising, but you could always use more money to fuel your StarCraft addiction (we've all been there).
