Morphology

penstock = pen + stock (opaque) = pen + stock

Although analyzable as 'pen' + 'stock', the sense 'large pipe or channel for water' is a specialized technical meaning not derivable by average learners from the components.

Etymology

Penstock comes from two simple parts: pen meaning 'enclose' (as in an animal pen) and stock meaning 'a wooden block' or 'barrier'. So a penstock is a pipe or channel that 'encloses' and can 'block' water, which explains its job of carrying and controlling water to a mill or turbine.
