plumb

To plumb a body of water, you measure its depth. To plumb a house, you connect all of its pipes. To make carpentry plumb, you get it exactly vertical.

Originally, the verb plumb only meant β€œto measure the depth of water.” These days, if you β€œplumb the depths” of something, you go in deep for knowledge and experience: your Heidegger seminar may plumb the depths of German Existentialism like Jacques Cousteau plumbed the depths of the ocean.
