Morphology

thoroughwort = thorough + wort (opaque) = thorough + wort

Although analyzable as 'thorough' + 'wort', 'wort' is archaic and the compound is an arbitrary plant name, so learners cannot reliably derive the sense.

Etymology

Thoroughwort comes from the old name for a plant whose stem looks like it goes 'through' the leaf; the name breaks into through and wort, where wort means 'plant'. So thoroughwort is a fitting name for this herb once used in folk medicine.
