Morphology

water + hyacinth

The meaning 'a hyacinth that grows in water' is directly and compositionally derived from combining 'water' (aquatic) with 'hyacinth' (a flowering plant); the compound simply specifies the habitat/type of hyacinth. This noun–noun modifier pattern is common across languages, so a B1 learner who knows both constituents would readily infer it refers to an aquatic plant.

Etymology

The name water hyacinth comes from how it looks: it is a floating plant with pretty flowers, so people joined water and hyacinth, a garden flower, to name it. Because it spreads very fast and makes thick mats that 'clog waterways', people remember it as a troublesome water weed.
