Though I may have a leaf or two And I may be made of wood, I am not a tree that grew. I'm where you set your food.

First three don't turn on, while the last three are a form of water. Some travel to it, some do it from home, either way, the tasks done, take their toll.

I’m medieval engineering’s way of saying, Let’s discuss this from a distance.

I'm a ring of light, a heavenly crown, A symbol of virtue, in a holy town, Above a head, I shine so bright, A sign of the sacred, in morning light.

I lift the bloom but am not the crown, I carry life from root to gown. Cut me short and words begin, Add me to study careers win. What am I?
