The aquatic plant known as water hyacinth has an interesting spelling that corresponds with its pronunciation. Using the International Phonetic Alphabet (IPA) transcription, the first syllable of the word is pronounced as /ˈwɔtər/ while the second syllable is pronounced as /hʌɪəsɪnθ/. The combination of the "h" and "y" sounds in the second syllable makes it unique, and the "th" at the end of the word is pronounced as an unvoiced dental fricative.

Water hyacinth refers to a perennial aquatic plant scientifically known as Eichhornia crassipes, belonging to the family Pontederiaceae. Originating from South America, it has become a globally recognized invasive species due to its ability to grow rapidly in various freshwater ecosystems. This free-floating herbaceous plant is characterized by its large, glossy, and rounded leaves, displaying a vibrant green color. It possesses bulbous petioles, which act as floats ensuring its buoyancy on water surfaces. Water hyacinth typically produces showy lavender to purple flowers that form on a central stalk above the water surface.
Growing in dense colonies, water hyacinth is renowned for its capability to reproduce quickly, making it a serious threat to the ecological balance of aquatic ecosystems. It can cause numerous environmental issues by impeding water flow, hindering sunlight penetration, and depriving native species of vital nutrients, thus leading to oxygen depletion and negatively impacting fish populations. The plant's high proliferation rate and capacity to form thick mats also impede recreational activities, water transportation, and irrigation systems.
Efforts to control water hyacinth include manual or mechanical removal, chemical treatments, and the introduction of natural enemies such as weevils, which feed on the plant. Additionally, utilizing water hyacinth for sustainable purposes like biogas production, compost, and craft materials can also aid in managing its proliferation. However, its resilient nature necessitates ongoing management strategies to prevent the adverse consequences of its invasive presence in various water bodies worldwide.
The word water hyacinth is composed of two parts: water and hyacinth.
The term water originates from the Old English word wæter or wætur, derived from the Proto-Germanic word watar. It can be traced back to the Proto-Indo-European root wod-or, meaning water.
