Main Translations

English: Delta

Thai: เดลตา (Delta)

Phonetic: Dehl-tah (in English pronunciation); เดล-ตา (in Thai Romanization)

Detailed Explanation: The word "delta" originates from the Greek letter Δ (delta), which resembles the triangular shape of a river delta. In English, it primarily refers to a geographical landform where a river meets a larger body of water, forming a fertile, triangular area of sediment (e.g., the Nile Delta). Usage scenarios include scientific, environmental, and everyday discussions about geography. Emotionally, it connotes stability and fertility due to its association with rich ecosystems, but it can also imply vulnerability in contexts like flooding or climate change. Semantically, it's neutral and factual, often used in technical or academic settings for precision.

Thai: ที่ราบลุ่มปากแม่น้ำ (Thi rab lum pak mae nam)

Phonetic: Tee rab loom pak mye nam
