Morphology

Centaurea + solstitialis

The element 'Centaurea' identifies a plant genus (daisy family), so a learner who knows that word can infer this is a species of plant; however 'solstitialis' is a Latin specific epithet with no transparent English meaning and does not convey the common name or properties (yellow star‑thistle, invasive). Because part of the meaning (that it is a plant species) is derivable but the full referent and attributes are not, the expression is only partially transparent to a B1 learner.

Etymology

Centaurea solstitialis The plant's name comes from two clear images: Centaurea links to the myth of a centaur who used the plant as a medicine, and solstitialis points to the 'longest day of summer' when its bright, star-like yellow flowers appear. So, the name helps you remember this yellow 'star-thistle' weed that blooms in summer and has sharp spines.
