IPA: /haɪˈdrɪlə/
KK: /haɪˈdrɪlə/
A type of aquatic plant that grows underwater, often found in freshwater environments, with long, narrow leaves arranged in whorls and small flowers.
The lake was filled with hydrilla, making it difficult for boats to navigate.
Hydrilla is derived from the Greek word "hydor" (meaning water) and the suffix "-illa" (a diminutive suffix in Latin, meaning small). Thus, hydrilla refers to a small water plant.
Think of 'water' ('hydor') and 'small' ('-illa') to remember that hydrilla is a small plant that grows in water.
