Pronunciation: [wˈɔːtə jˈam] (IPA) 
The spelling of "water yam" can be a bit tricky. The word is pronounced /ˈwɔːtər jæm/, with the stress on the first syllable. The "water" part is easy enough, but the second word can be confusing since the "y" is not pronounced as a consonant but as a vowel, similar to the "i" in "bit". This gives the "ya" sound, and the "m" at the end is pronounced as normal. So, "water yam" is pronounced as "WAW-tuh yam".
Water yam, scientifically known as Dioscorea alata, is a perennial climbing vine belonging to the Dioscoreaceae family. It is a tuberous root vegetable that is widely cultivated for its edible and nutritious tubers. The water yam is typically grown in tropical and subtropical regions, particularly Southeast Asia, Africa, and the Pacific Islands.
The water yam plant produces large, elongated tubers with rough, brownish skin. The flesh of the tuber can vary in color from white to pale yellow and has a crisp texture, akin to a potato, when cooked. It is known for its starchy taste and high nutritional value, containing dietary fiber, vitamins, and minerals.
Water yam tubers are versatile and can be utilized in various culinary applications. They can be cooked, boiled, roasted, grilled, or fried, and are often used in soups, stews, curries, and stir-fries. Due to their starch content, they can also be processed into flour or starch, which can serve as a thickening agent in food preparations.
In addition to its culinary uses, water yam has also been traditionally used for its potential medicinal properties. It is believed to have anti-inflammatory, antioxidant, and anti-diabetic properties, and has been used in traditional medicine to treat various ailments.
Overall, water yam is a valuable root vegetable that offers both nutritional benefits and culinary versatility, making it a popular and important food source in many tropical regions around the world.

The word "water" in "water yam" refers to the fact that this type of yam plant, scientifically known as Dioscorea alata, thrives in wet and marshy conditions.
