Morphology

St + John's + wort

The phrase is compositionally built from 'St' (Saint) + 'John's' (possessive name) + 'wort' (a plant), so a learner who knows those words will readily infer it refers to a plant associated with Saint John. This follows a common naming pattern (PERSON's + 'wort' = a plant named for that person), so the core referent is directly derivable even if specific species or medicinal uses require extra knowledge.

Etymology

St John's wort gets its name from St John because its bright yellow flowers bloom around St John's Day in late June. People used to hang the wort over doors to 'ward off' evil, so the name reminds us of its old use as a protective, healing plant.
